Perform the following steps:

Check for common issues: If imports fail, check the status details. Hovering over the status may show a "file not found" error.
File size: Ensure that each file is not larger than 200 MB.
Handling 504 errors:
- 504 errors often occur due to large numbers of files in a single S3 bucket. If there are over 1000 files in one folder, it can cause timeouts.
- To resolve this, split the folder into multiple folders with fewer files (<=100 for each folder). The backend S3 import fetch file API currently has a timeout of 5 minutes.
