Python errors during ARM deployment

[ashraaghav]

I created an issue in the other repo Azure/data-factory-deploy-action#22, but maybe here is more relevant because the error is raised in Azure/arm-deploy.

I'm trying to deploy Azure Data Factory using the Azure/data-factory-deploy-action (this uses Azure/arm-deploy) on a self-hosted runner. I've followed the steps similar to this article.
I install python, powershell and azure for powershell in the workflow, build the ARM templates and deploy. But when I try to deploy, I encounter this error with python asyncio: AttributeError: '_UnixSelectorEventLoop' object has no attribute '_ssock'.

The problem is it succeeds half the time without any changes in the codes. Why do only some of the deployments work and some don't?

Could it be because some dependency is missing in the runner? The runners are clean and I install the dependencies in the previous steps.

I've included a full log below:

> Run Azure/[email protected]
> Run if('false' -ne 'true') { Install-Module -Name Az -Scope CurrentUser -Repository PSGallery -Force }
> Run /runner/_work/_actions/Azure/data-factory-deploy-action/v1.2.0/PrePostDeploymentScript.ps1 `
