Sorry, but Peter was faulted not for false doctrine, but failure for hypocrisy. Paul explicitly tells us that Peter had allowed his community to eat with gentiles, but that Peter acted hypocritically in stopping that practice. For this, Paul calls him a hypocrite, TWICE.

It was doctrinal issue that was resolved by the Jerusalem council ... The doctrinal question was were Gentiles bound by the law...

Yes, it was a doctrinal issue that was resolved at the Council of Jerusalem. The Protestant view is that Peter made his case and that James decided the issue. The Catholic view is that Peter laid out the doctrine and James implemented it. So when people come from James and induce Peter into sinning, does he complain to James? No! He complains to PETER... because Peter has authority over James and should have told James’ people to shove off!
