Ill-Formed Payload Structure.
The logical document could not be processed as it was not well formed XML structure.
This error occurs when there is prohibited characters existing in the STP data. The most common field that this will affect would be the Given Name and Surname fields.
Prohibited Characters include:
- Special symbols such as &, <>, %, #, @, $, *, and + are invalid in most contexts due to their use in XML/JSON formatting or potential to disrupt downstream systems.
- Repeated hyphenation or apostrophes: While apostrophes (e.g., O'Connor) are permitted, repeated instances (e.g., O''Connor) or consecutive hyphens (e.g., Smith--Jones) trigger validation errors.
- Non-alphanumeric characters: Emojis, diacritics (unless standardized to ASCII equivalents), and non-printable Unicode characters (e.g., line breaks) are invalid.
