Hi. I’m trying to develop [this](https://github.com/mjsir911/discourse-telegram-auth) plugin and am having issues with external dependencies. My dependency is specified in `plugin.rb` with `gem 'omniauth-telegram', '0.2.1'` which is the recommended way to require dependencies I believe? I’m bringing it into the docker container with this: ```plaintext hooks: after_code: - exec: cd: $home/plugins cmd: - git clone https://github.com/mjsir911/discourse-telegram-auth.git ``` Results in this error: ```plaintext I, [2022-09-21T07:17:21.579540 #1] INFO -- : > cd /var/www/discourse && su discourse -c 'LOAD_PLUGINS=0 bundle exec rake plugin:pull_compatible_all' I, [2022-09-21T07:17:22.713904 #1] INFO -- : discourse-telegram-auth is already at latest compatible version docker_manager is already at latest compatible version I, [2022-09-21T07:17:22.714304 #1] INFO -- : > cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate' rake aborted!

I’ve attempted a few things and made a PR to your plugin and the fix seems to be working. [https://github.com/mjsir911/discourse-telegram-auth/pull/1](https://github.com/mjsir911/discourse-telegram-auth/pull/1)
