BUNDLE_VALIDATION_ERROR on Make.com: The scenario stops executing and displays a BundleValidationError alert bubble indicating that data types mismatch or required fields have missing values. — Root cause: This error occurs when an incoming bundle passes empty values or mismatched data types into a module field configured as mandatory. Make.com rejects the execution because the target application's schema expects a specific data type or string but receives null or an unexpected array. — If the error persists despite correcting all field mappings and implementing fallback functions, reach out to Make.com customer support through the Help Center ticket system. Provide your scenario link, export blueprint JSON, and specific execution history IDs showing the payload details.
