Error caused by changing a comment to have only a slash command
You can cause an error in the GUI by performing the following steps:
- Make a comment on an MR with anything in it
- Edit that comment, replace all the content with just a slash command, e.g.
/label ~test
- When you submit that edit, the changes will have been performed (comment is deleted, label is added), but the GUI now throws an error presumably because it can't find the comment you were editing to re-display it
I think this is likely a frontend bug
