Hello, I am trying to install a plugin, when I try the command below I get the error.

cd /var/discourse
./launcher rebuild app

I get this error

found a tab character that violate indentation while scanning a plain scalar at line 100 column 13 -e LANG=en_US.UTF-8

So I can’t rebuild my discourse. Does anybody know how to fix it?

Discourse does not allow tab in containers/app.yml file. You are allowed to use space. I think you added a tab while adding the plugin. Remove the tab and use white space and build your discourse again. Hope the problem will be solved.
