21902: InvoiceTag length must be between 0 and 32

This error appears when a Messaging request includes an InvoiceTag value that is outside the supported 0 to 32 character length range.

• The InvoiceTag value is longer than 32 characters.
• The request sends an InvoiceTag value that does not fit the supported length validation.

• Shorten InvoiceTag to 32 characters or fewer before you send the request.
• Validate the InvoiceTag length in your application so the request cannot exceed the supported range.
