What's Wrong?

Our .fig file for our design system is 47.7MB and I keep running into an error that says "Couldn’t read [File Name]". The file I previously uploaded was 5.8 MB and worked perfectly. What is the limit on the file size? Can we up the limit? Is it because of another issue entirely?

What Should Happen?

Claude should be able to take in larger file sizes, or, UX-wise, let us know the maximum file size it can handle.

Error Messages/Logs

3. Upload .fig file.
