Hi Jef -
What type of file is included in your table? Is it by chance image files?
The Table API does not currently support direct file upload. However you have some options here:
- How to write image to tables through API - this thread discusses encoding image files in Base64 and storing them in text fields as a workaround.
- Posting files to tables from outside Tulip - this thread discusses uploading files to external services and storing the URL in Tulip.
