Moodle API token is required

Error message

Moodle API token is required

What it means

A ConnectorMissingCredentialError raised in MoodleConnector.load_credentials when the credentials dict has no moodle_token key (or it is falsy). The token is the sole auth mechanism for Moodle's web service API, so the connector refuses to construct its MoodleClient without it.

Solutions

1. Generate a token in Moodle (Site administration > Plugins > Web services > Manage tokens) and pass it as credentials['moodle_token'].
2. Verify the dict actually contains a non-empty string under exactly 'moodle_token' before calling load_credentials.
3. If sourced from env/secrets, confirm the secret is mounted and the name matches.

Example fix

# before
connector.load_credentials({})  # raises ConnectorMissingCredentialError('Moodle API token is required')

# after
connector.load_credentials({'moodle_token': os.environ['MOODLE_TOKEN']})

token = credentials.get("moodle_token")
if not isinstance(token, str) or not token.strip():
    raise ValueError("moodle_token missing or empty")

When it happens

Trigger: Calling load_credentials({'moodle_token': ''}) or a dict missing the key entirely — e.g. the credential payload from the UI/backend dropped the field, or an env var was empty.

Common situations: Connector credential form saved without pasting the token; env var MOODLE_TOKEN unset in the deployment; key typo (token vs moodle_token); token value of empty string after JSON round-trip.
