@lamb-j / @arsenm,
What is the process we are following to create PR's on amd-main? I see Jacob changing base branch from amd-staging to amd-main.
lamb-j changed the base branch from amd-staging to amd-main
This base branch update is causing CI side issues. I am looking in to it. We also had github connection errors like 502 (Bad Gateway) and 403 (Forbidden access - random occurrence) recently which has caused some disruption to CI from Yesterday evening. I see this connection errors have auto resolved as of now.
