Signorg cannot be empty. What do you mean?
When doing some operations or processing, it is necessary to provide a valid signature or signorg.

Signature or identifier is used to prove the legitimacy and validity of identity, right confirmation or authorization. If this signature or identifier is empty, it means that no valid certificate or authorization is provided, which will cause the operation to fail or be rejected. Therefore, when performing operations involving signatures or identifiers, it is necessary to ensure that the correct signatures or identifiers are provided.
