19010: Invalid contact search request

Twilio returned this error because the contact search request is invalid. This usually means the request body, search filters, or query format does not match the requirements for the Contact API.

• The request includes an invalid or unsupported search parameter.
• A required field is missing from the search request.
• The search filter uses an incorrect data type or an invalid value.
• The request body is not formatted as valid JSON.
• The search expression does not match the supported schema for the Contact API.

• Review your request payload and confirm that every search parameter is supported by the Contact API.
• Make sure all required fields are included and that each value uses the expected format and data type.
• Validate that the request body is well-formed JSON before sending the request.
• Remove unsupported filters or parameters from the search request.
• Check your Contact API implementation against the Unified Profiles documentation and update the request format as needed.
