Error MessageeSign server error. Document SignedError occured when uploading attachment for document (a3R7F000000Q4M8UAK) to salesforce.

App Expert Reply:
– The document ID (a3R7F000000Q4M8UAK) is referring to an eSign doc ID.
– Use global search in Salesforce and search for document ID *a3R7F000000Q4M8UAKb*.
– By viewing the eSign user can analyze if anything is wrong with it and can view activity history.
– With this error, the signature status was most likely manually changed to “signed” by a user rather than automated update based on app workflows. If a user tried to change the unsigned Doc to “signed” status, the server recorded it as error since there is no document saved.
