Error message

None of the specified GitHub repositories could be found for owner: {self.repo_owner}

What it means

ConnectorValidationError raised on HTTP 404 when 'repositories' contains a comma (multi-repo mode). Because GitHub hides private repos you cannot access as 404, this means none of the listed repositories were visible to the credential under repo_owner.

Solutions

Check each 'owner/repo' spelling via the GitHub UI or gh repo view owner/repo.
If repos are private, grant the token access (repo scope / fine-grained allowlist) — remember GitHub returns 404 for invisible private repos.
Confirm repo_owner matches the account that actually hosts the repos.

Defensive patterns

Strategy: validation

Validate before calling

for name in repositories.split(','):
    if not repo_exists(gh, owner, name.strip()):
        collect_typo(name.strip())  # note: private+no-access also looks like a typo

Try / catch

try:
    connector.validate_connector_settings()
except ConnectorValidationError as e:
    return 400, str(e)

Prevention

Copy repo names exactly from the GitHub URL; beware renames/transfers.
Remember GitHub 404s invisible private repos — check token access before assuming a typo.

When it happens

Trigger: 404 from the validation probe with repositories='a,b' — every name wrong, private-without-access, or the owner segment of owner/repo is incorrect.

Common situations: Typos in repo names; repo renamed or transferred; private repo with a public-only token (GitHub reports 404, not 403); owner set to the wrong org.
