19041: Invalid or missing Custom Field input

The request body contains invalid custom field data. This error occurs when a required custom field value is missing, when a custom field value does not match the expected format, or when the same custom field is provided more than once in the request.

• A required custom field value was omitted from the request body.
• A custom field value was included in an invalid format or with an unsupported value.
• The same custom field was submitted multiple times in a single request.
• The request body structure does not match the expected schema for the resource you are creating or updating.

• Review the request body and confirm that each required custom field is included.
• Validate each custom field value before sending the request.
• Remove duplicate custom fields from the request body.
• Check the expected request parameters for the endpoint you are calling and make sure the payload matches the documented schema.
• Retry the request only after correcting the invalid custom field input.
