Please could you try running these commands

```plaintext
./launcher enter app
cd /var/www/discourse/plugins
su discourse
for d in *; do echo "$d: $(git -C $d config --get remote.origin.url)"; done 

```

Every plugin should have a remote URL shown in the list. I suspect, based on the error, that one of them doesn’t 🤔

Expected output is something like

```plaintext
chat: https://github.com/discourse/discourse.git
discourse-automation: https://github.com/discourse/discourse-automation
discourse-chat-integration: https://github.com/discourse/discourse-chat-integration.git
...

```
