Before uploading a data set file to AWS S3 source type:
- Prepare the file in a test folder; check that the file format meets the S3 data source file parameters.
- Move the file to the production folder only after you have verified that the file is complete.
- If the file timestamp is epoch seconds or epoch milliseconds, don't define a timezone - it will be treated as an error.
- The file must be formatted using UTF-8 or ASCII.
