We recently updated our AWS Add-on to version 6.3, after which all Generic S3 inputs stopped ingesting.
Noticed the following error being repeated during every S3 API call. "parse_csv_with_delimiter'"
The data within our s3 bucket was a tar or .gz extension with either json or xml format, after the upgrade our previous AWS s3 inputs seemed to have defaulted to csv format.
Ended up recreating several AWS Generic S3 inputs using a start date from when the Add-on was updated, which allowed the previous missed logs to ingest again.
