Description

I am using the latest version of github/gh-ado2gh 1.19 and I am able to generate the migration script for moving repos from ADO to our own GHE enterprise, the repo's move over generally without issue however the pipeline re-wiring just doesn't seem to work anymore.

Here's an example of the logs for the rewiring step for a repo using the classic pipelines.

[2025-10-01 13:51:37] [INFO] Rewiring Pipeline to GitHub repo...
[2025-10-01 13:51:37] [INFO] Looking up pipeline ID for: \EmailService - PR Dev

[2025-10-01 13:52:40] [WARNING] GitHub is currently experiencing availability issues.  See https://www.githubstatus.com for details.

There is a branch policy in place but it seems like this isn't detected and the pipeline isn't even updated to use our GHE even if the status check hasn't been configured.

Reproduction Steps

Run a rewire-pipeline command using PAT token authentication for ADO and GHE

gh ado2gh rewire-pipeline --ado-org "{org-name}" --ado-team-project "{project-name}" --ado-pipeline "{pipeline-path}" --github-org "{gh-org}" --github-repo "{repo}" --service-connection-id "{connection-id}"

and get the above output in response.

Manually re-wiring

In an attempt to re-wire the pipeline just so that the repo and pipeline have been moved together for this repo I updated the pipeline to point to the relevant GHE repo and added the status check for a PR, however when a PR is raised the status just get's stuck saying "Expected — Waiting for status to be reported", if I manually trigger the pipeline for the relevant branch the status updates in GH so it seems like the PR trigger isn't working in ADO as I can see the webhook request was sent with a 200 response.

Any help with this would be great - thanks in advance,
Adam
