Autoloader: Read old version of file. Read modification time is X, latest modification time is X

I'm recieving this error from autoloader. It seems to be stuck on this one file. I don't care when it was read and last modified, I just want to ingest it. Any ideas?

java.io.IOException: Read old version of file s3a://<file-path>.json. Read modification time is 1713910814000, latest modification time is 1713925112000

@stevenayers-bge Autoloader is designed to work best with immutable files. If files are mutable (i.e., they can be updated), it is recommended to set cloudFiles.allowOverwrites = true to ensure that the latest version of the file is read.

Please refer to the below documentation for more details:
