When you start the "File Q&A" app (https://github.com/openai/openai-cookbook/tree/main/apps/file-q-and-a/nextjs) in the file upload screen it says:

You can upload 30MB per file and unto 75 file. (see attached)

But the console shows the error of 4MB limit (see attached)

What should be the correct limit? how do I fix this? is it really 75 file is the limit?
