error: ReadableStream has already been used

[steve-py96]

In version 1.3.0 a bug was introduced where a response is re-used and causes the error from the title to occur

This handler seems to cause it:

app.get(path, page, {
    detail: {
      hide: true
    }
  })

Reproduction
Just do a fresh project with the most minimalistic setup: new Elysia().use(swagger()).listen(3000);

PS: awesome framework, thx for it <3 - if you want I can create a PR to fix this ig (doesn't seem too difficult on first sight :D, but choice is yours ofc)

Likely seeing this too. 1st time it works but after that I see:

Error: Body is unusable: Body has already been read

As a response. Downgrading to the swagger 1.2.2 allows it to work again, though I'm sure without the full 1.3 features.

Also using the node plugin (Not sure if that matters here though).

For anyone who still got problem Error: Body is unusable: Body has already been read or Response.clone: Body has already been consumed. when using with node adapter, I think I found temporary workaround to resolve this problem

import { Elysia } from 'elysia'
import { openapi } from '@elysiajs/openapi'
import { node } from '@elysiajs/node'

const openapiPlugin = openapi()

const response = openapiPlugin.router.history[0]?.handler as unknown as Response
const hooks = openapiPlugin.router.history[0]?.hooks

let body: string = ''

let app = new Elysia({ adapter: node() }).use(openapiPlugin).get(
  '/openapi',
  async () => {
    if (!body) body = await response.text()

    return new Response(body, {
      headers: {
        'content-type': 'text/html; charset=utf8',
      },
    })
  },
  hooks
).listen(8080)
