When I remove the plugin, it will rebuild and run correctly. I also tried adding a random other plugin (`discourse-bbcode`). That caused the same issue.
Any pointers how to debug more? @ozgurkuru how did you solve this?

Hi!
The issue is that you’re trying to add the plugin in the wrong location.
Looking at the end of your `app.yml`:
```plaintext
## Plugins go here
## see https://meta.discourse.org/t/19157 for details
hooks:
after_code:
- exec:
cd: $home/plugins
cmd:
- git clone https://github.com/discourse/docker_manager.git
## Any custom commands to run after building
run:
- exec: echo "Beginning of custom commands"
## If you want to set the 'From' email address for your first registration, uncomment and change:
## After getting the first signup email, re-comment the line. It only needs to run once.
#- exec: rails r "SiteSetting.notification_email='discourse@mail.kyub.com'"
- exec:
cd: $home/plugins
cmd:
- git clone https://github.com/discourse/discourse-oauth2-basic.git
- exec: echo "End of custom commands"
```
Notice that you have the default docker\_manager plugin installed on line 8, then you added your plugin stanza down on line 19. You’ll want to remove these lines (16-19):
```plaintext
- exec:
cd: $home/plugins
cmd:
- git clone https://github.com/discourse/discourse-oauth2-basic.git
```
Then add `- git clone https://github.com/discourse/discourse-oauth2-basic.git` directly below the docker manager line, ensuring the indentation matches.

Thanks @jomaxro! That was probably it, I’ll try it on Monday.

Work like a charm. Thanks again @jomaxro 🙂
