A certain voluminous merge request cannot be opened: HTTP 502

Summary

We have a very large merge request that cannot be opened:

https://gitlab.com/nexarts/qidigo/merge_requests/545

I suspect that creating the diff takes too much time and the server hits maximum exec time.

We tested other MRs in our project and they don't exhibit the same behaviour

Steps to reproduce

Simply clicking on the link if user has access to the project will trigger a 30ish second load time, then an error page similar to this (see Screenshot section)

Example Project

Follow this link: https://gitlab.com/nexarts/qidigo/merge_requests/545

What is the current bug behavior?

HTTP 502 will occur upon clicking the link

What is the expected correct behavior?

The Merge Request can be accessed and consulted
