There may be several reasons for this error, such as:
1. User registration code or name is incorrectly filled, such as spelling error, format error, etc.
2. The user registration information does not match the information filled in the request. For example, the company name is filled in the request, while the personal name is filled in the user registration information.
3. The user registration information has not been updated or verified, such as the user registration information has changed, but it has not been updated in time, or the user registration information has not been verified.

1. Carefully check the user registration code and the name of the applicant (representative) in the request to ensure that it is filled in correctly.
