what is the size limit for a file attachment via API


I have build a webpage that uploads attachments to a row in smartsheet. It works fine for 12 MB file.

But I have been trying to upload a file which is 100MB via API to a row, but everytime I get below error:

{"response": {"statusCode": 500, "reason": "Internal Server Error", "content": "<< text/html;charset=UTF-8 content type suppressed >>"}}
