UNKNOWN error when trying to use NodejsFunction

[NightWatchman]

Every time I try to use new NodejsFunction I get a spawnSync error that seems to be related to aws-lambda-nodejs not being able to succesfully execute the parcel command, but I can't figure out exactly why. Running the parcel command manually works fine.

Reproduction steps

Run the cdk deploy command

Seems from the stack trace that the error comes from ramda? Do you still see the error when removing this dependency? Can you share a reproductible example?

[NightWatchman]

I'll look into it more and see if I can come up with a minimal project that reproduces it.

Closing for now

Same problem here, with all release up to 1.38.0

Only on Windows 10, works with with WSL2.

[jogold]

You need docker with v1.38.0.

[d2kx]

Thank you. That also does not work

Docker is asking for an absolute path but getting a relative one it looks like, but I'll try to look into it and file another new issue later.

Not sure I'll want to have Docker installed just for this library, so I'll likely switch back to the regular @aws-cdk/aws-lambda library and build the function myself in the future.

The problem on Windows should be fixed with #8140.
