I have almost the same Problem using Gatsby. Just to let you know so that you can check out my topic as well:

Not found, Problem fetching Git Organization Repos

Hi, my proplem is, that I can not log into my admin of my deployed site, which is comming from an organisation repository. For the organization repository at /admin/ I can type my username and password but afterwards and error is popping up in the UI:“Not found” I guess it has to do with the authenification in Github, but we cannot find any problem.Do you have any suggestions what could be the problem? Setup: Gatsby, Github, Netlify Kind of Repository: Organization Repository Netlify Back…

If you have any solution please let me know.
