How to rectify this error?

Hi @malavikavenu96​, from the log snippet in the screenshot, it appears that you're using a Directory and File Pathnames reader (shortname PATH), can you try using an S3Connector instead if you're trying to read data from S3?

If I've missed the mark on the format you're connecting to, it might help to share a bit more context on what data you're trying to read and your current reader parameters.
