Question: how to debug hang in node-fetch? (likely environmental issue)

On my Windows 10 dev box, Node 12.17.0, I’m seeing the following code hang:

let result = await fetch("https://sadchonks.com/kitteh-512.png"); // success, 200
let buffer = await result.buffer(); // This hangs, never finishes. No errors, no result. Just hang.

I’m trying to figure out why this hangs. Stepping into the debugger, I reach into consumeBody function, but neither body.on('error', ...) nor body.on('data', ...) never fires:

I’ve also tried de-asyncing my code by using .then(…) chains without async. Still no dice; it hangs on the same call to .buffer().

Any suggestions for debugging this hang?

It still happens and happen accidently. It’s so hard to reproduce and try catch is not work to handle this.

t’s bugged in long run system and became unpredicted. anybody have solution?

I use node 13.6.0

able to reproduce by fetching images in loop, buffer is hitting maximum size and just hanging.
