System.ApplicationException: 'Signature field 'SignatureField1[0]' is not defined

I am trying to add a digital signature to a field with the following code, and getting the following exception:

System.ApplicationException: 'Signature field 'SignatureField1[0]' is not defined.'

I am using the following code:

var signature = new PdfFileSignature(pdfDocument);

using var fileStream = File.OpenRead("C:/users/conner.phillis/documents/output.pfx");

var pkcs = new PKCS7(fileStream, "password") { ShowProperties = false };

signature.SignatureAppearance = "C:/users/conner.phillis/downloads/keymark.jpg";

signature.Sign(signatureField.FullName, pkcs);
signature.Save("C:/temp/output.pdf");

The exception is coming from the last line, the save method. The full name of the field is
topmostSubform[0].Page1[0].SignatureField1[0]

The name of the field is null for some reason. Is this some sort of bug or am I doing something wrong?

I am not a paid support customer. Is there any way for me to watch the status of this ticket? or a time until it is expected to be complete?
