GLSP editor not working in Theia when launched using VScode backend config

[glsp-bot]

Hi,

I need to debug some backend code, therefore I am launching the Theia instance using Vscode launch config. But GLSP editor is not working when launched using VSCode config, whereas it works fine when I start Theia using standalone script 'yarn start'.
My other non-GLSP extensions are working fine in both modes.

Also, none of the breakpoints on the GLSP code is getting hit.

launch.json -

{
'type': 'node',
'request': 'launch',
'name': 'Launch Browser Backend 2',
'program': '${workspaceRoot}/browser-app/src-gen/backend/main.js',
'args': [
'--hostname=0.0.0.0',
'--port=3000',
'--no-cluster',
'--debug',
'--app-project-path=${workspaceRoot}/browser-app',
'--plugins=local-dir:${workspaceRoot}/browser-app/plugins',
'--hosted-plugin-inspect=9339'
],
'env': {
'NODE_ENV': 'development'
},
'sourceMaps': true,
'outFiles': [
'${workspaceRoot}/browser-app/src-gen//*.js',
'${workspaceRoot}/browser-app/lib//.js',
'${workspaceRoot}/node_modules/@theia//li**b//.js',
'${workspaceRoot}/node_modules/@eclipse-glsp//lib//*.js',
'${workspaceRoot}/mamba-table-rule-glsp-editor/lib//*.js'
],
'smartStep': true,
'internalConsoleOptions': 'openOnSessionStart',
'outputCapture': 'std'
}
I am running the GLSP server as a standalone process therefore passing '--debug' in args.
I have configured 5007 as the default port in the code, therefore not passing in arguments -

createLaunchOptions(): Partial {
return {
jarPath: JAR_FILE,
additionalArgs: ['--consoleLog', 'false',
'--fileLog', 'true',
'--logDir', SERVER_DIR],
serverPort: getPort(PORT_ARG_KEY, DEFAULT_PORT)
};
I can see the below message in Chrome dev tools -
