Now I update dify to v1.1.3, error is nor shown. But it directly tell me that "Invalid file link 文件链接无效" .

I'm sure that the oss file is right, because I can use browser to download the picture.

@dosubot[bot] commented on GitHub (Mar 25, 2025):

The issue you're experiencing with the "Invalid file URL" error in Dify version 1.1.3 is likely due to stricter validation rules for file URLs in this version. The validate_after method in the File class now checks if the remote_url is a string and starts with "http". If the URL does not meet these criteria, it raises a ValueError with the message "Invalid file url" [1].

To resolve this, ensure that your file URL is correctly formatted and starts with "http". If the URL is correct and still not working, you might want to check if there are any additional network or configuration issues affecting the URL validation.
