The DBConnector action in Studio keeps throwing a 500 Internal Server Error when passing a JSON object with nested arrays to the input_data field. The SQL query works fine in the database directly, but the action fails silently in the logs with Failed to parse input parameters. Is there a known serialization limit or format requirement for complex types here?
DBConnector doesn’t handle nested JSON in the input_data field directly. You’ll need to serialize the object to a string first using the ToJson action, then pass that string to the connector.
