One of my power automate workflow, which has been running normally for months, has faced with a problem. The workflow gets the excel attachment of an email (get attachment v2) and creates it onto sharepoint site. The original file in the email can be correctly opened by desktop excel app, while the file on sharepoint site is corrupted. After comparing the output of the get attachment node with the successful runs, I have found out that "vary":"Accept-encoding" is missing in the header. Does anybody know whether this is the cause of the file corruption? Why this parameter is missing in the header?
