Not possible to use Terraform wrapper with pwsh shell on windows based self-hosted runner

[ankitatdnv]

Hi,

I am trying to use windows based self-hosted runners for terraform deployment, but when I use the terraform-wrapper: true, None of the Terraform commands get executed and give the following output:

However when I run it with terraform-wrapper: false, all Terraform commands works fine, but then I cannot use -detailed-exitcode, as with this plan fails due to non zero exit code.

Hi @ankitatdnv 👋

have you tried using bash as the shell? As per our usage section in the Readme:

When running on windows-latest the shell should be set to Bash.

Thanks @ansgarm for the reply, I have tried using bash, but it fails with the following error:
shell: C:\Windows\system32\bash.EXE --noprofile --norc -e -o pipefail {0}

Windows Subsystem for Linux has no installed distributions.
Distributions can be installed by visiting the Microsoft Store:

Although I have the bash available in the self hosted runner:

Hi @ankitatdnv 👋

Is your self-hosted runner running Windows or Ubuntu? The screenshot looks like Ubuntu 👀

It's running windows with WSL enabled, it's the bash command prompt

Ah, right, thanks! I haven't used WSL yet, so the output confused me a bit.

I'm afraid it's out of scope for me to debug your self-hosted runner. Are you able to create a reproduction repository that I can use to debug?

That said, there's also potentially another way for you to use --detailed-exitcode: You'd have to write some PowerShell logic that handles the non-zero exit code returned from terraform plan.

Where to write that logic, as of now I am having below given step for catching the exitcode and setting it in the step output variable
name: Terraform Plan Output
id: plan-output
run: |
echo "exitcode=$?" >> $GITHUB_OUTPUT
