@vercel/blob - `put` Error: The Edge Function "api" is referencing unsupported modules:

Export

Vercel Blob - I am attempting to upload a `102k` file.

## The fix

Set `edge: false` in your SolidStart config for the route that uploads blobs. The Blob `put` call pulls in Node modules (`net`, `http`, `stream`, crypto) that the Edge runtime does not support, which is what the 'referencing unsupported modules' error means. The reporter confirmed uploads work with `edge: false` (the function then runs as a Serverless Function instead of an Edge Function). Edge mode stayed unsupported in the thread, so keep the upload path on serverless.
