BadResource Error with Request.text() in Deno

[PutziSan]

Version: deno 2.1.1 (stable, release, x86_64-unknown-linux-gnu)

The following Deno server code produces seemingly random BadResource: Bad resource ID errors:

Deno.serve(async (req) => new Response(await req.text()));

Observed Behavior

The error probably occurs when the TCP connection is closed before the request body is fully read. Example error:

BadResource: Bad resource ID
    at readableStreamCollectIntoUint8Array (ext:deno_web/06_streams.js:1060:23)
    at InnerBody.consume (ext:deno_fetch/22_body.js:163:14)
    at consumeBody (ext:deno_fetch/22_body.js:255:34)
    at Request.text (ext:deno_fetch/22_body.js:351:16)
    at file:///<...>/server.ts:1:50
    at ext:deno_http/00_serve.ts:382:26
    at ext:deno_http/00_serve.ts:573:33
    at eventLoopTick (ext:core/01_core.js:175:7) {
  name: "BadResource"
}

A Wireshark capture of a failed request shows the client closing the connection immediately after sending a POST request.

Expected Behavior

The server should not throw an error or throw a more descriptive error.

Context

I encountered this error while load testing my Deno server using wrk. The error occurred only on the end of a load test run, but not on every run.
