Not able to add Node Options --experimental-vm-modules in debug

[selvakumar-invicara]

We follow ESM, so to make jest to be work I used below command,

node --experimental-vm-modules node_modules/.bin/jest

I have given this command in jestrunner.jestCommand to make jest runner to work for RUN. But It doesn't work for debug and never seeing any options pass this argument. If I add it in debugOptions then it append it as below

/usr/local/bin/node ./node_modules/.bin/jest --experimental-vm-modules

which gives an error as the argument should be before jest.

Is there any way to solve this problem

I've tried to get this work by putting this in my settings.json:

"jestrunner.debugOptions": {
    "runtimeArgs": "--experimental-vm-modules"
},

Unfortunately, the flag is not injected correctly. It adds a space in between each character in the flag:

/path/to/node - - e x p e r i m e n t a l - v m - m o d u l e s ./node_modules/.bin/jest

In case it's relevant, I am using zsh as my shell.

Turns out the args needed to be in an array:

"jestrunner.debugOptions": {
    "runtimeArgs": ["--experimental-vm-modules"]
},

Not sure where I got the idea to use a single string lol.

Hi,

Can you please share your settings (package.json, settings.json, jest-config.json, etc). I am trying to set this up using *.mjs files and I can't debug them with this extension.

I am getting this error: Cannot use import statement outside a module

Like @eltoroit , I could really use a settings.json sample file.

Right now, it's as if jestrunner.* settings were ignored altogether. I even tried giving jestrunner.jestPath an unexisting path just to make sure it fails; it didn't.
