I am running a gremlin-server, and using restful api to query it. But I'm confused with this error below :
{"message":"Error encountered evaluating script: g.V().next()"}
but it is such a simple script.
for other script like "100-1" and "g", the query result is just OK. I have checked lots times for spelling and character. And I also have checked the gremlin-server logs, but there was no related records. So I ask for your help, Thanks!
You would run into that error if you don't have any data in the graph because it is an unchecked traversal. You should try a query like:
if (g.V().hasNext()) { g.V().next() }
If you're using Apache TinkerPop 3.1.2 or later, you would have seen a more informative stack trace in the Gremlin Server logs:
[WARN] HttpGremlinEndpointHandler - Invalid request - responding with 500 Internal Server Error and Error encountered evaluating script: g.V().next()
org.apache.tinkerpop.gremlin.process.traversal.util.FastNoSuchElementException

I am trying to authenticate user using FormLoginHandler and Postgresql Database with SqlAuthentication.
But I get the following error:
Jun 15, 2022 1:14:34 PM io.vertx.ext.web.RoutingContext
SEVERE: Unhandled exception in router
io.vertx.ext.web.handler.HttpException: Unauthorized
Caused by: io.vertx.core.impl.NoStackTraceThrowable: Invalid username/password
I am providing the right credentials.
The code snippet is:
SqlAuthenticationOptions sauthopts = new SqlAuthenticationOptions();
sauthopts.setAuthenticationQuery(AUTHENTICATE_QUERY);
SqlAuthentication authenticationProvider = SqlAuthentication.create(sqlClient, sauthopts);
router.route("/secure/*").handler(RedirectAuthHandler.create(authenticationProvider, "/login.html"));
FormLoginHandler formLoginHandler = FormLoginHandler.create(authenticationProvider);
router.route("/loginhandler").handler(formLoginHandler);
Please let me know if I am missing something here; or point me to a sample example.
Thanks in Advance.
Your setup doesn't show anything abnormal at first sight. For security reasons, we cannot "just" log the authentication data, as it would be a critical OWASP bug and security vulnerability.
My best guess is that probably is something not totally correct with the query, so this means you have now 2 options:
debug the application and see the query that is being sent + the arguments
prepare a small complete example that shows the bug and open an issue in vert.x so we can debug it further.
If you're upgrading from an older version, be aware that in vert.x 4.2.0 some changes were made to the base64 encoding to keep it consistent across modules. This could be a reason why authentication could fail as the encoded hashes may be slightly different. If you're just doing 4.3.0 from the start, then this would not be a problem.
Good day,
I am trying to use robot framework to test a soap based api. I tried using the RobotFramework-Soap library first. I tried a sample case and it works but as soon as I put in my api link it does not work. Im not sure if it is because my api link contains an api.
N.B. due to confidentiality I am unable to post the actual api link. But it is in the format shown below.
*** Settings ***
Library SoapLibrary
Library OperatingSystem
*** Test Cases ***
Example
Create Soap Client http://000.000.000.000:8000/SomeService?wsdl
${response} Call SOAP Method With XML ${CURDIR}/request.xml
${text} Get Data From XML By Tag ${response} AddResult
Log To Console ${text}
Save XML To File ${response} ${CURDIR} response_test
When I run the above test. It fails with following error:
ConnectionError: HTTPConnectionPool(host='xxx_cert', port=8000): Max retries exceeded with url: /SomeService?xsd=xsd0 (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 11001] getaddrinfo failed'))
I even tried using the suds library as well. and when i do a simple test as follows:
***Test Cases***
Example
Create Soap Client http://000.000.000.000:8000/SomeService?wsdl
I get the following error: URLError: urlopen error [Errno 11001] getaddrinfo failed
I did some searching and I found that it could be related to the port. But Im not sure how to resolve this issue.
Any assistance would be greatly appreciated.
Thanks,

The solution was to edit the local host file to cater for the web service. That seemed to solve all the problems.
How can I configure tomcat to show the actual stacktrace during a 500 error on a REST call? Currently I only get a "System error occurred - 500" type of message. Is there a plugin/configuration setting that will allow me to add more detail in the returned error?
I see a similar question: Tomcat not showing full stack trace in Error Report for Http status 500 error but this suggests going to the server logs. I would like (at least in development mode) to see the error at the client side.
I am trying to run REST API from Load Runner but unable to do it. Every times its throws below exception
Action.c(4): Error -26612: HTTP Status-Code=500 (Internal Server Error) for "http://ipaddress/LoyaltyApi/api1/loyaltycard/linkcard", Snapshot Info [MSH 1 1] [MsgId: MERR-26612]
My code :
Action()
{
lr_think_time(10);
web_custom_request("LinkCards",
"URL=http://ipaddress/LoyaltyApi/api1/loyaltycard/linkcard",
"Method=POST",
"Resource=0",
"EncType=application/json",
"Mode=HTTP",
"BodyFilePath=linkcards.json",
LAST);
return 0;
}
I have tested the same URL with POST parameter in POSTMAN and it's working fine without any issue.
I am very new in this technology so unable to solved the issue. Please help.
I am very new in this technology....
Assuming your management has moved you to this role, have they provided you with training on the tool and a mentor for a period of time. If not they have set you up for failure.
I am using eclipse indigo(javaEE) and apache tomcat 7.0.23. the jsp code
pstatement = connection.prepareStatement(queryString);
pstatement.setString(1, name);
pstatement.setString(2, city);
pstatement.setString(3, phone);
updateQuery = pstatement.executeUpdate();
is giving error as the requested resource jsp1/prepared_statement_query.jsp is not available.
The simple .jsp file executes properly and shows the successful connection, but not for insertion into the database. I am not getting whether there is problem with the database connection or the running of the server?
Is it any kind of 404 error? is the file "prepared_statement_query.jsp" not in the place where it should be?
If the error is - "404 Requested Resource Not Found" then find the file in proper place.
And Kindly post the complete stack trace for better understanding of the issue.
