Environment variables do not resolve correctly in Asset URLs

[mnlmaier]

Description

We are using several Environment Variables for the plugin. All variables are set correctly in .env, but — for some reason — they don't seem to be resolved. I am getting output URLs in the following format:

https://s3.$AWS_BUCKET_REGION.amazonaws.com/$AWS_BUCKET_NAME/images/redacted/redacted.jpg

This is an excerpt of our project.yaml

In our .env file, all variables are set correctly and only once.

Is there anything that we are missing here, should this not be working?

Thanks in advance!

Do you have "Files in this filesystem have public URLs" set to true or false? If it's true, what is your "Base URL" set to?

It's worth noting that environment variables aren't parsed out of the Base URL setting. If you want that to be set based on an environment variable, it has to start with one.
