• New People.ai connector with OAuth2 authentication and automatic token refresh on 401 errors
• Implements retry logic with exponential backoff for transient 5xx and connection errors
• Syncs two tables: activity (base activities) and participants (participant details)

The update() function is missing a required validate_configuration() function call. According to SDK guidelines, every connector must implement and call validate_configuration() at the start of the update() function to validate configuration parameters (api_key and api_secret in this case).

Add this function before update():

def validate_configuration(configuration: dict):
    """
    Validate the configuration dictionary to ensure it contains all required parameters.
    This function is called at the start of the update method to ensure that the connector has all necessary configuration values.
    Args:
        configuration: a dictionary that holds the configuration settings for the connector.
    Raises:
        ValueError: if any required configuration parameter is missing.
    """
    required_configs = ["api_key", "api_secret"]
    for key in required_configs:
        if key not in configuration:
            raise ValueError(f"Missing required configuration value: {key}")

Then call it at the start of update():

def update(configuration: dict, state: dict):
    """..."""
    validate_configuration(configuration)
    # rest of the code
