To understand the core of the issue
text/event-stream is the official media type for Server Sent Events (SSE); it will prefix data bits with a data: prefix and you can also choose your prefix to change the meaning of that piece of data for the client. This media type is for browsers, as they support that using the EventSource JavaScript API.
      You may need an additional loader to handle the result of these loaders. - occurs for useHead

Have u deleted node_modules and installed again

Seems webPackHotUpdate plugin is not installed

Nuxt bridge installs webpacker and hotReloading module
https://github.com/nuxt/bridge/blob/c80e571b42d715d362f0b40161641043cedbe2ee/packages/bridge-schema/build.config.ts
I was using nuxt 2.15 and I upgraded it to nuxt bridge

But I am facing, template compilation issues and I have rollback everything.

I will wait for offcial guide migrating to Nuxt3
Cheers
          
Thanks @psahni -- I was missing the correct import statement for fromNodeMiddleware:
import { fromNodeMiddleware } from 'h3';
But doing a clean install and adding the hooks setting in config did help. It's still not perfect, I expect a fix in Nuxt-bridge from the nuxt team, but it's better! Thank you.
