How to remove merge request from GitLab server

Question

I created a merge request on gitlab (local) server. Now whenever I click on the merge request, the request times out with error 500. Before that I used to get an error code 504

Answer 1

I don't know if this works with CE as well, but at least EE has an API endpoint to delete merge requests:

curl --request DELETE --header "PRIVATE-TOKEN: " https://gitlab.example.com/api/v3/projects/4/merge_request/85
