Typically, the above exception is thrown if you attempt to certify a Dynamic XFA PDF.

Certifying a PDF requires a Signature field on the form. In case no Signature field is present, the Certify operation attempts to add one. Adding Signature programmatically is not possible on a Dynamic XFA PDF. Therefore, the operation fails with the above exception indicating that creating a signature was not possible.

Add a Signature field (the field is invisible) on the Dynamic XFA PDF, and configure the Certify operation to place the certification on that Signature field.
