Node.js debugger has a default value of --inspect-brk=PORT without specifying this in the script-CodePudding

When I run my mocha tests in debug mode, Node.js debugger has a default value used as the --inspect-brk= value. Without specifying it in the script, my test script looks like that

--timeout=15000 --appName=ejbrowser --role=adminUserOne --env=tst --reporter=spec tests/api/ejbrowser/devices/all.spec.js --failureFatal=1

But when I run it with debug mode the script that is being executed is:

C:\Program Files\nodejs\node.exe" C:\repos\yyc-api-ui-automation\node_modules\mocha\bin\mocha --inspect-brk=57629 --appName=ejbrowser --role=adminUserOne --env=tst --timeout=60000 --slow=2000 --reporter=mochawesome tests/ui/-common/-health-checks-lvl1/all.spec.js --browserClient=chrome --failureFatal=1 --timeout 0 --ui bdd --reporter "C:\Program Files\JetBrains\IntelliJ IDEA 2021.3\plugins\NodeJS\js\mocha-intellij\lib\mochaIntellijReporter.js"

Where does this value --inspect-brk=57629 come from?

The project that I work on doesn't accept this parameter in commandLineArgs and I had to modify it to accept { partial: true} which is not perfect. So I am trying to understand what is populating this value.

I use IntelliJ idea 2021.3.2 Ultimate.

How to disable the debug mode (node's inspect features)

Remove your debug configurations from intellij using the "-" button. Or just run you application in "run mode", not using the "run debug" mode from the IDE.

How to choose the debug port number

57629 is just the default port number for debug configured by intellij.

To change it, open intellij and go to Run | Edit Configurations | Add New Configuration | Attach to Node.js/Chrome

Then, change the Port field value.

I found what caused it. My temporary directory contains spaces and there's no way to escape spaces when passing it to NODE_OPTIONS unfortunately. So the IDE uses the explicit --inspect switch. As a work around I specified a different TEMP dir in Help > Edit Custom VM Options (Djava.io.tmpdir=C:\tmp) and it solved the issue.
