Error response from daemon: invalid environment variable: =::=::\

[bronvic]

I'm trying to add an env file to my configuration and see an error: Error response from daemon: invalid environment variable: =::=::\ My configuration is a pytest run using docker-compose interpretator

The thing is that I can use this file when running docker-compose manually. The error is present even if env file is empty

I'm working on Windows using WSL2
