I'm trying to configure the DAP debugger in Neovim for a typescript application.
I added the DAP plugin:
use "mfussenegger/nvim-dap"
I also have a config.lua file containing the adapter and configuration:
local status_ok, dap = pcall(require, "dap")
if not status_ok then
return
end
dap.adapters.chrome = {
type = "executable",
command = "node",
args = {os.getenv("HOME") .. "/dev/dap-debugger/vscode-js-debug/out/src/debugServerMain.js", "45635"}
}
dap.configurations.typescript = {
{
type = "chrome",
request = "attach",
program = "${file}",
debugServer = 45635,
cwd = vim.fn.getcwd(),
sourceMaps = true,
protocol = "inspector",
port = 9222,
webRoot = "${workspaceFolder}"
}
}
When, under nvim in my typescript application project, I try to start the debugger with the :lua require'dap'.continue() command, I get the error:
Debug adapter didn't respond. Either the adapter is slow (then wait and ignore this) or there is a problem with your adapter or `chrome` configuration. Check
the logs for errors (:help dap.set_log_level)
But the ~/.cache/nvim/dap.log DAP log shows no error:
[ DEBUG ] 2022-04-12T08:49:37Z+0200 ] ...nvim/site/pack/packer/start/nvim-dap/lua/dap/session.lua:776 ] "Spawning debug adapter" {
args = { "/home/stephane/dev/dap-debugger/vscode-js-debug/out/src/debugServerMain.js", "45635" },
command = "node",
type = "executable"
}
[ DEBUG ] 2022-04-12T08:49:37Z+0200 ] ...nvim/site/pack/packer/start/nvim-dap/lua/dap/session.lua:965 ] "request" {
arguments = {
adapterID = "nvim-dap",
clientId = "neovim",
clientname = "neovim",
columnsStartAt1 = true,
linesStartAt1 = true,
locale = "en_US.UTF-8",
pathFormat = "path",
supportsRunInTerminalRequest = true,
supportsVariableType = true
},
command = "initialize",
seq = 0,
type = "request"
}
I can set breakpoints with the command:
lua require'dap'.toggle_breakpoint()
I also installed the VSCode Js debugger with the following commands:
git clone https://github.com/microsoft/vscode-js-debug
cd vscode-js-debug/
npm i
gulp
I can see that my Chrome browser is listening on the 9222 port:
chrome 208069 stephane 118u IPv4 1193769 0t0 TCP 127.0.0.1:9222 (LISTEN)
If I run the debugger manually, I can see it starts on the given port number:
09:16 $ node ~/dev/dap-debugger/vscode-js-debug/out/src/debugServerMain.js 45635
Debug server listening at 45635
I'm on NVIM v0.7.0-dev
My Angular application is started and responds all right.
UPDATE: The debugger I was trying to use is not on DAP standard. I guess I need to find an alternative.
The VSCode Chrome debugger is deprecated and has been replaced by the VSCode JS debugger. The VSCode JS debugger is compatible with all browsers. But the VSCode JS debugger is not DAP compliant. So the VSCode Chrome debugger is still being used for now.
Installing the debugger:
git clone git#github.com:microsoft/vscode-chrome-debug.git
cd vscode-chrome-debug
npm install
npm run build
Configuring the debugger:
local function configureDebuggerAngular(dap)
dap.adapters.chrome = {
-- executable: launch the remote debug adapter - server: connect to an already running debug adapter
type = "executable",
-- command to launch the debug adapter - used only on executable type
command = "node",
args = { os.getenv("HOME") .. "/.local/share/nvim/lsp-debuggers/vscode-chrome-debug/out/src/chromeDebug.js" }
}
-- The configuration must be named: typescript
dap.configurations.typescript = {
{
name = "Debug (Attach) - Remote",
type = "chrome",
request = "attach",
-- program = "${file}",
-- cwd = vim.fn.getcwd(),
sourceMaps = true,
-- reAttach = true,
trace = true,
-- protocol = "inspector",
-- hostName = "127.0.0.1",
port = 9222,
webRoot = "${workspaceFolder}"
}
}
end
local function configureDap()
local status_ok, dap = pcall(require, "dap")
if not status_ok then
print("The dap extension could not be loaded")
return
end
dap.set_log_level("DEBUG")
vim.highlight.create('DapBreakpoint', { ctermbg = 0, guifg = '#993939', guibg = '#31353f' }, false)
vim.highlight.create('DapLogPoint', { ctermbg = 0, guifg = '#61afef', guibg = '#31353f' }, false)
vim.highlight.create('DapStopped', { ctermbg = 0, guifg = '#98c379', guibg = '#31353f' }, false)
vim.fn.sign_define('DapBreakpoint', { text = '', texthl = 'DapBreakpoint', linehl = 'DapBreakpoint',
numhl = 'DapBreakpoint' })
vim.fn.sign_define('DapBreakpointCondition',
{ text = 'ﳁ', texthl = 'DapBreakpoint', linehl = 'DapBreakpoint', numhl = 'DapBreakpoint' })
vim.fn.sign_define('DapBreakpointRejected',
{ text = '', texthl = 'DapBreakpoint', linehl = 'DapBreakpoint', numhl = 'DapBreakpoint' })
vim.fn.sign_define('DapLogPoint', { text = '', texthl = 'DapLogPoint', linehl = 'DapLogPoint', numhl = 'DapLogPoint' })
vim.fn.sign_define('DapStopped', { text = '', texthl = 'DapStopped', linehl = 'DapStopped', numhl = 'DapStopped' })
return dap
end
local function configure()
local dap = configureDap()
if nil == dap then
print("The DAP core debugger could not be set")
end
configureDebuggerAngular(dap)
end
I'm having a problem with my web project. It is my first time when i try connecting database. I want to connect database to see that working. I use Postgres and have set up a database. I want to connect by using the following code :

You have a typo in config's property names in the definition of default values for private variables. It should be jdbc instead of jbdc:
private var dbUrl = appConfig.property("jbdc.url").getString()
private var dbUser = appConfig.property("jbdc.username").getString()
private var dbPassword = appConfig.property("jbdc.password").getString()

I am trying to view an app via "ionic serve" but I get this error. I have looked at other subjects but have never seen a runtime error. I tried all of their solutions but I would still have the same error page. Here is what I see:
And to be honest, I am not the coder of this app, but I have bought it from a store. But, I know some here and there. If there is a simple solution to fix this, that would be amazing!
The first error link is pointing to here:
_this.initialData();
var operating_system = '';
var admob = {};
if (_this.device.platform.toLowerCase() == 'android') {
operating_system = 'android';
admob = {
banner: settings['admob_android_banner'],
interstitial: settings['admob_android_interstitial']
};
}
The second error link is pointing me to here:
SafeSubscriber.prototype.__tryOrUnsub = function (fn, value) {
try {
fn.call(this._context, value);
}
catch (err) {
this.unsubscribe();
throw err;
}
};
The third error is pointing to here:
SafeSubscriber.prototype.next = function (value) {
if (!this.isStopped && this._next) {
var _parentSubscriber = this._parentSubscriber;
if (!_parentSubscriber.syncErrorThrowable) {
this.__tryOrUnsub(this._next, value);
}
else if (this.__tryOrSetError(_parentSubscriber, this._next, value)) {
this.unsubscribe();
}
}
The fourth error is pointing to here:
Subscriber.prototype._next = function (value) {
this.destination.next(value);
};
The fifth error is pointing to here:
var /** #type {?} */ response = new Response(responseOptions);
response.ok = isSuccess(status);
if (response.ok) {
responseObserver.next(response);
// TODO(gdi2290): defer complete if array buffer until done
responseObserver.complete();
return;
}
Here is the code I get in cmd:

It seems that platform is not returned properly and that's why it's null.
You didn't include your constructor so i have no idea how your constructor looks like, but the following code snippet is returning platform name properly using the Device plugin you're using in your code.
import { Device } from '#ionic-native/device';
constructor(private device: Device) {}
......
if(this.device.platform.toLowerCase()=='android'){
// Your logic here
}
This happens because you're running ionic serve on web and the cordova platform isn't available there. Ionic Native returns {} when a property doesn't exist (when cordova isn't available), and it throws a console warning for developer assistance.
When one try to retrieve data from {} object then it will return null.
Please try adding below code:
import { Platform } from 'ionic-angular';
//add it in constructor as follows:
constructor( public platform: Platform){
}
//add platform check
if (this.platform.is('cordova')) {
//add your code here
}else{
console.log("Plugin not supported on web");
}
We are using:
• Drools Execution Server that came with Drools 5.0.x
• Drools Guvnor 5.2 configured with active directory
The execution server and guvnor run on the same Tomcat and use the same port.
With the execution server you can have a listener for each package within the configuration file. I have two such files, from-file-system.properties that points to a local directory where a drools binary package is manually deployed. This works fine.
But I try to use with-guvnor.properties which points to a package binary on 5.3 Guvnor. Here is the file:
name=ndipiazza
newInstance=true
# Absolute path of the directory containing pc.drl: placeholder replaced by Ant.
url=http://localhost:9109/drools-guvnor/rest/packages/NDD_Test/binary
poll=10
I get the following error:
RuleAgent(ndipiazza) INFO (Mon Jun 18 18:11:32 EDT 2012): Configuring package provider : URLScanner monitoring URLs: http://localhost:9109/drools-guvnor/rest/packages/NDD_Test/binary
RuleAgent(ndipiazza) WARNING (Mon Jun 18 18:11:34 EDT 2012): Was an error contacting http://localhost:9109/drools-guvnor/rest/packages/NDD_Test/binary. Reponse header: {null=[HTTP/1.1 401 Unauthorized]
Some sort of authorization error very likely related to the active directory configuration within Guvnor 5.2.
This used to work for us just fine with an earlier version of Guvnor.
How can I fix this issue?
So we isolated the problem today. Drools Server 5.0.x cannot support a URL endpoint when it has authentication of any sort.
I reported a bug: https://issues.jboss.org/browse/JBRULES-3554
Without these changes, this will not work.
drools-core's org/drools/agent/HttpClientImpl.java
These two methods need to have authentication added in (marked by START and END NDD), and obviously switched with your username/password.
public LastUpdatedPing checkLastUpdated(URL url) throws IOException {
URLConnection con = url.openConnection();
HttpURLConnection httpCon = (HttpURLConnection) con;
try {
// **** START NDD *****
BASE64Encoder enc = new sun.misc.BASE64Encoder();
String userpassword = "ad-user" + ":" + "ad-password";
String encodedAuthorization = enc.encode( userpassword.getBytes() );
httpCon.setRequestProperty("Authorization", "Basic "+
encodedAuthorization);
// **** END NDD *****
httpCon.setRequestMethod( "HEAD" );
String lm = httpCon.getHeaderField( "lastModified" );
LastUpdatedPing ping = new LastUpdatedPing();
ping.responseMessage = httpCon.getHeaderFields().toString();
if ( lm != null ) {
ping.lastUpdated = Long.parseLong( lm );
} else {
long httpLM = httpCon.getLastModified();
if ( httpLM > 0 ) {
ping.lastUpdated = httpLM;
}
}
return ping;
} finally {
httpCon.disconnect();
}
}
public Package fetchPackage(URL url) throws IOException,
ClassNotFoundException {
URLConnection con = url.openConnection();
HttpURLConnection httpCon = (HttpURLConnection) con;
try {
// **** START NDD *****
BASE64Encoder enc = new sun.misc.BASE64Encoder();
String userpassword = "ad-user" + ":" + "ad-password";
String encodedAuthorization = enc.encode( userpassword.getBytes() );
httpCon.setRequestProperty("Authorization", "Basic "+
encodedAuthorization);
// **** END NDD *****
httpCon.setRequestMethod( "GET" );
Object o = DroolsStreamUtils.streamIn( httpCon.getInputStream() );
if ( o instanceof KnowledgePackageImp ) {
return ((KnowledgePackageImp) o).pkg;
} else {
return (Package) o;
}
} finally {
httpCon.disconnect();
}
}
Mystery solved.
