"Error: Resource Group [...] could not be found." ideas?

[serazsanett]

Recently we started getting this error in our datafactory deployment job. The resource group we're trying to deploy to is certainly there, and the credentials were confirmed to be correct multiple times. No other error is shown and no explanation is given by the action for this error. We're using azure/login@v2 and azure/arm-deploy@v2, but changing the versions to older ones don't work either.

Any ideas on how to fix?
