[ISL] gh graphql fail to get "statusCheckRollup" of a commit

[nicktogo]

When ISL is running graphql YourPullRequestsQuery, it gets error:

{"type":"FORBIDDEN","path":["search","nodes",0,"commits","nodes",0,"commit","statusCheckRollup"],"extensions":{"saml_failure":false},"locations":[{"line":36,"column":15}],"message":"Resource not accessible by integration"}

perhaps that's some permission change in my company repo, but this error breaks the ISL just for not getting the state, can we gracefully handle such error?

I get similar issue, statusCheckRollup == 'SUCCESS' yet my test signals are undefined.

actually deleting all stale PR branches (including the sapling-pr one) fixed the problem for me! thanks FB team!

Actually looking further into it, I think it's just pulling the status of first commit in the stack, i.e as soon as I commit, it shows up as green check marked, despite that commit's status being PENDING
