Curations failing on website

The creation of PRs is failing when done through the ClearlyDefined website if you do not have permissions to the curated-data repo (or at least that is how it seems).

I am able to submit PRs with no issue using this account since I have push permissions to the curated-data repo. The same goes for the other curators. However, we have a new person helping and they are not able to have PRs created when logged in. They only go through when logged out of the site. I tried this with another account that is not a part of ClearlyDefined and ran into the same issue.

I tried submitting through Edge, Chrome and FireFox with the same result. I do see that it creates the branches in the curated-data repo but stops there. Checking the browser for errors shows:

```
api.clearlydefined.io/curations/gem/rubygems/-/adiwg-mdtranslator/1.4.0.beta3?expand=prs:1
Failed to load resource: the server responded with a status of 404 ()

api.clearlydefined.io/curations:1
Failed to load resource: the server responded with a status of 500 ()
```

@elrayle @qtomlinson Are either of you able to help with this issue?
