Problem merging pull requests

Hi! I'm having troubles merging a pull request, it gets a 500 response code when calling a service task, and gets the response:

{"type": "error", "error": {"message": "Something went wrong", "id": "0948fc2f0a364b4caa36674b76c90206"}}

I've tried declining the pull request, and creating a new one, but it appears to have the same problem. The final error is a javascript error that can't get responseJSON from undefined.
