CodeBuild CLIENT_ERROR authorization failed for primary source: fix the connection
Complete solution
'CLIENT_ERROR: authorization failed for primary source' means CodeBuild could not access the repo.
[Stack Overflow q64300151]: 'CLIENT_ERROR: authorization failed for primary source' means CodeBuild could not access the repo. For GitHub or Bitbucket sources, the OAuth connection or access token expired or was revoked: reconnect the source in the CodeBuild project settings. For CodeCommit or S3 sources, check the CodeBuild service role has read permission on the repo. Re-test with a trivial buildspec after reconnecting so you isolate auth from build logic.
Context: Source authorization errors are connection or role problems, not buildspec problems.
Evidence
Source: Source authorization errors are connection or role problems, not buildspec problems.
