Actual behaviour

return error

Can the issue reliably be reproduced?

Yes

Steps to reproduce the issue

Find instructions and code for reproduction in docker here:
https://github.com/eike-hass/iota-sdk/tree/bug/network-error-in-dockerized-node22/bindings/wasm/reproduction

Or use local Node 22 and run node index.js in reproduction folder

says it pulled docker.io/library/node:21

Edit: my bad, I have it set to node:21 in the reproduction

[Thoralf-M]

So yes after changing it to 22 it also fails for me, couldn't figure out what exactly causes this yet, but I found some additional info that might help
First, not all requests are broken, nodeinfo works, even getting another output works. So to me it seems node.js does something wrong with the body, if it exceeds some size (your output contains a metadata feature and is larger than the output id that works (basic output without features)

const { Client, initLogger } = require("@iota/sdk-wasm/node");

(async () => {
  try {
    initLogger()
    const client = new Client({ primaryNode: "https://api.testnet.shimmer.network/" });

    // Works
    console.log(await client.getInfo());
    // Works
    console.log(await client.getOutput("0x0e67475116d5e5a0c845c8f89bb15e3b9f7059001e8e674443d45d153c921bf90000"));
    // Fails
    console.log(await client.getOutput("0x9e190f35188fa7986205a8fed2dd69554d7a3218805709ee04cc73a87bc9cd090000"));
    // Also fails
    console.log(await client.getBlock("0xee4936315c60809a48665b7b85225788c4c56abad46147ab3483e1fc499213a1"));
  } catch (error) {
    console.log(error)
  }
})();

Logs for output where it works and the one that doesn't work:

We should try reqwest in wasm alone next, probably the issue happens without iota-sdk and large bodies
