App.yml Error after Installing Plugin

I tried installing a new plugin and ran into this error after trying to rebuild app.yml. I am looking at the file but am unable to identify what the error is. I have removed the added .git from the file and the error still persists.

uknown did not find expected key while parsing a block mapping at line 10 column 1 -e LANG=en_US.UTF-8

Try linting the file:

sudo apt-get install yamllint
yamllint /var/discourse/containers/app.yml
1 Like

I see a lot here. Nothing referring to the error I am getting on restart. There are quit a few entries for

missing starting space in comment

and

line too long (85 > 80 characters)

Nothing special in the line 10? Can you share the yaml (clean passwords)?

I am on a web console I will have to post later, when I can pull the full file.

My app.yml
