WebSockets - what happens when worker is upgraded

When we upgrade our Worker - does CloudFlare terminate active sockets? We think we're seeing behavior where an old version of a worker is around for some time with a live socket - probably with multiple open sockets. Is this expected behavior?

How to read FormData entry in CloudFlare?

CloudFlare Workers do not support the Blob or FileReader type. How can I read the 'body' of a multipart/form-data post ?

const formData = await request.formData();
const rawStream = formData.get("entry-name");
// how to get the string value of rawStream? .toString() yields [Object, object]

const formData = await request.formData();
const rawStream = formData.get("entry-name");
// how to get the string value of rawStream? .toString() yields [Object, object]

Promise will never complete

We're seeing an error Promise will never complete in logs but cannot locate the code and am not sure what can cause it. I saw this comment in a conversation with @kenton https://discord.com/channels/595317990191398933/773219443911819284/868646357425086585 But still cannot recreate this error. A simple return await new Promise(() => {}) yields the eponomous The script will never generate a response (https://zuplo.com/blog/the-script-will-never-generate-a-response-on-cloudflare-workers/) error. Which seems distinct. Any ideas what could cause this?
