Hi @john c cahill 
Thank you for your patience. I'll look into this for you. 
In the meantime, there's a reported error "2024 eSignature Errors When Submitted Using One Click Signature: Request Not Sent in ProSeries". If you haven't tried it already, the workaround is eSignatures can be sent from the Client Screen. 
Keep me updated if this is resolved for you otherwise I'll keep you updated on this thread.
