Invalid Envronment Variable

I'm using the workflow file below.
But I'm receiving the following error on the "Run Azure/aci-deploy@v1" step:

> Error: Error: The environment variable name in container 'test' of container group 'test' is invalid. A valid environment variable name must start with alphabetic character or '_', followed by a string of alphanumeric characters or '_' (e.g. 'my_name', or 'MY_NAME', or 'MyName').

From what I can tell, it is either a problem with a multiline string, spaces in the environment variable or both. I have tried surrounding the environment variable with single and double quotes. I even tried to save it as a multiline Github secret.

Any guidance or indications of what could be the problem are appreciated.
