gh-gei tool (github API) doesn't work

We’re using gh-gei tool to perform a migration from one Github Cloud Enterprise to other one (EMU), and since last Friday, the migration command doesn’t work ( gh gei migrate-repo --github-source-org "Amplifon-Org" --source-repo "Symphony_Internal_Test_Repo" --github-target-org "Amplifon-Organization" --target-repo "Symphony_Internal_Test_Repo" )

Also, I’ve checked Github Status, and it seems that in same Friday, Github Apis had some reported issues (That seems that should be solved, however it looks like not).

Today we have to perform a migration of several repos again, but it seems that we can’t do it.

[7:38] [ERROR] System.NullReferenceException: Object reference not set to an instance of an object.
