Netlify is unable to find a Github organisation repo in order to create a new site.
Create a new site > Github > Install Netlify screen popup (Github login) > Choose the organisation and repo.
Once the org repo has been selected, you are redirected to https://api.netlify.com/github/app-installed?installation_id=9410206&setup_action=update where you then see a blank screen and the popup does not close automatically. The site will not create and you see in the dashboard:
No repositories found
This can happen when Netlify doesn’t have access to the repositories in an account.
Configure the Netlify app on GitHub, and give it access to the repository you want to link.
I can see the Netlify app in my “Installed GitHub Apps” section on Github so authorizing was no problem, its the last step that seems to fall over.
