I want to implement automation to download excel files from SharePoint and create new version for the passed decision table rule and upload the data.

I have tried using Java code to upload downloaded file to static export and use that path in Import document function to upload data to decision table. was able to create excel file in static export but I am getting below error while executing. Not sure how to debug this issue. Has someone faced similar issue?

"Incorrect file. Please attach the same .xlsx file that was exported earlier"
