Error: spawn EINVAL running autorest legacy on windows

[jwaltz-bah]

A recent Node JS update includes a breaking change to patch a security vulnerability: https://nodejs.org/en/blog/vulnerability/april-2024-security-releases-2

When running autorest csharp v2 on Windows, the "spanw EINVAL" error occurs and stops execution.

Tested with both Node v21.7.3 and v18.20.2 (the patch was applied across all major Node versions)

Command:

autorest --input-file=swagger.json --csharp --legacy --add-credentials --namespace=MyApp.Model.Data --output-folder=MyApp.Model\Data

Console output:

Suggested solution from the Security Release announcement:

If the input to spawn/spawnSync is sanitized, users can now pass { shell: true } as an option to prevent the occurrence of EINVALs errors.

Should be labeled v2--haven't tested on v3

We're getting pressure from IT security to move away from NodeJs 18.17.1.0 but we can't as long as this error persists. When can we expect a fix?
