Thanks Haris the quick turnaround. I am able to download the signed documents on disk with the code sample that you shared. But I needed to extract the files inside the zip in memory as we have a subsequent workflow which needs the documents in memory. But I believe, w.r.t. eSignLive, the document zip with the signed files is being returned successfully. So, the problem is not at your end for sure. Thanks for all the help.
I need to find out the issue in the code we are using to extract the files. Thanks again.
