I have created a new Balena Application and moved my device to this new Balena application.  
I also created a new branch `dev_pa` starting from my master branch and copy pasted (locally) the same small change to my docker-compose.yml file.

When I tried to push this local branch to my new Balena application then I get a different error:  
see ["[Error] Could not parse compose file" when pushing a local branch to Balena](https://forums.balena.io/t/error-could-not-parse-compose-file-when-pushing-a-local-branch-to-balena/16777)

What is strange that pushing the same changes from the master branch doesn’t give an error (see also ["[Error] Could not parse compose file" when pushing a local branch to Balena](https://forums.balena.io/t/error-could-not-parse-compose-file-when-pushing-a-local-branch-to-balena/16777))
