I'm building a chrome devtools extension with TypeScript + React
My Steps
loaded unpacked dist on chrome://extensions
open a new tab with devtools page(and the window alerts "this is content script")
clicked my extension panel
the error appears on chrome://extensions
Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist.
Context
devtools://devtools/bundled/devtools_app.html?remoteBase=https://chrome-devtools-frontend.appspot.com/serve_file/#a6b12dfad6663f13a7e16e9a42a6a4975374096b/&can_dock=true&dockSide=undocked

But if I click the "inspect views background page` manually before step 2, everything works well.
I think the background should start up automatically in production. Did I miss something?
index.tsx
chrome.devtools.panels.create("Garbanzo",
"favicon.ico",
"devtools.html",
function (panel) {
// code invoked on panel creation
let backgroundPageConnection: chrome.runtime.Port
panel.onShown.addListener(function (window) {
// when the user switches to the panel, check for an elements tab
// selection
backgroundPageConnection = chrome.runtime.connect({
name: "devtools-page"
});
});
panel.onHidden.addListener(function () {
backgroundPageConnection.disconnect()
});
}
);
contentScript.chunk.js
alert("this is content script")
background.chunk.js
chrome.runtime.onConnect.addListener((port) => {
alert("OK");
})

Please help!
Much obliged.
I have been using the chalkboard plugin for a reveal presentation. As it is written on the github page (https://github.com/rajgoel/reveal.js-plugins/tree/master/chalkboard), I saved the drawings in a json file by pressing d (as far as I can tell, the data was correctly stored in the json file) and then I added the line src: "prova/cb.json", to the initialization for chalkboard and loaded the presentation with ?print-pdf.
However, when I open the presentation, there is no trace of the drawings that should be loaded.
This is the html of a minimal (non) working example...
Does anyone know what's going on?

I've a flutter web app that'll run on the localhost perfectly but when I deploy it to firebase I get a blank page. In setting up firebase hosting I selected build/web as my public directory. I ran flutter build web which compiles the app. The build directory is created. My firebase.json file looks fine.(pos-ap/build/web for the public directory is correct)
{
"hosting": {
"public": "pos-app/build/web",
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
],
"rewrites": [
{
"source": "**",
"destination": "/index.html"
}
]
}
}

I'm not really familiar with web stuff. And apologies I can't really offer any more info. I suppose the only clue is that it works on localhost but not when deployed.
My root directory is..
|-pos-app
|-consumer-app
|-firebase.json
I'm trying to deploy pos-app which is a flutter app.
Please, if anyone knows how to solve that..

Please help me to resolve this.
Thanking you
You are missing:
'ag-grid-ng2': 'node_modules/ag-grid-ng2',
i.e.
var map = {
'ag-grid': 'node_modules/ag-grid',
'ag-grid-ng2': 'node_modules/ag-grid-ng2',
};
