The following code throws an error in Deno versions 1.17 and upwards:

const { instance, module } = await WebAssembly.instantiateStreaming(
  fetch("https://wpt.live/wasm/incrementer.wasm"),
);

const increment = instance.exports.increment as (input: number) => number;
console.log(increment(41));

deno run -A wasm.ts

Deno 1.16:

42

Deno 1.17:

error: Uncaught (in promise) Error: request or response body error: error reading a body from connection: unexpected end of file
    at async Object.pull (deno:ext/fetch/26_fetch.js:104:24)

Deno 1.25:

error: Uncaught (in promise) Error: request or response body error: error reading a body from connection: unexpected end of file
    at async Object.pull (deno:ext/fetch/26_fetch.js:119:24)

const { instance, module } = await WebAssembly.instantiateStreaming(
  fetch("http://wpt.live/wasm/incrementer.wasm"),
);

change https:// to http:// working as expected, not sure why. i'm new to deno. @dsherret any idea?

Maybe the problem is caused by the rustls, discussed in 13058. And is there any plan to fixed?

I think you are right @eryue0220, this is probably the same issue as #13058. Closing as duplicate.
