I know with Next they have a framework limit of 4mb that can be passed through API routes, wouldn’t surprise me if Remix had something similar since they too have hosting.
I’ve worked around it by creating a temporary API key and uploading directly via the client instead of an API route https://pinata.cloud/blog/how-to-upload-to-ipfs-from-the-frontend-with-signed-jwts/
