When using the Microsoft SharePoint Upload a File action in your Zaps, you see the error message "Error code 404: 404 FILE NOT FOUND". You may see this error when setting up a Zap or in the details of a Zap run in your Zap history.

Causes

This happens when:

The file you're trying to upload exceeds the maximum size is 10MB.
The provided file URL is not publicly accessible or downloadable.
The Site field contains an invalid URL format. It should only include the portion after /sites/.

How to fix it

To fix this issue:

Check that your file is 10MB or less.
Test that the file's URL is accessible or downloadable.
- Open an incognito browser and copy and paste the URL into the address bar.
- Press Enter on your keyboard.
- One of the following will happen:
  - The file will display in the browser window if it’s a viewable format.
  - The browser will download the file to your computer.
  - If the file cannot be accessed or downloaded, you may see an error message. This means Zapier cannot access the file. Learn more about sending files in Zaps.
- If the Site field is a mapped field with your SharePoint site's full URL, use a Formatter step to split the site name from the rest. The site name is the portion that comes after /sites/ on your URL.
