We have a feature that lets users upload Excel files from the web UI (compress and store files in an S3 bucket) and later on, shows the data in Excel in a web view and lets users edit that data. In the beginning worked fine but recently with more usage of the web app, After 2-3 days of app usage by our users this feature became unresponsive(no errors we can see) and the node server lost the ability to read these Excel files from the node server.
