Error reading GitHub URLs

[ericvoshall]

Expected Behavior

GitHub Discovery and URL reading should work without issue when using GitHub Apps.

Actual Behavior

Receiving errors when trying to create Location entities.

[1] 2022-07-20T17:51:54.360Z catalog warn Unable to read url, TypeError: Cannot read properties of undefined (reading 'some') type=plugin entity=location:default/generated-06fa68e2c829fc2780525e800261d718fa7da58f

Steps to Reproduce

1. Have Backstage configured to use GitHub Apps for GitHub integration
2. Configure a github-discovery Location or add a url location that is a GitHub URL.
3. Run Backstage
4. Error output from the catalog when it attempts to create Location entities

Context

We didn't have an issue until we updated to 1.4.0.

• I tracked down the commit in Backstage that seems to have introduced this issue
• I also found a related issue (the type definitions appear to be off) which includes a functional workaround
