http-body = "1.0"
http-body-util = "0.1.2"
http_v02 = { package = "http", version = "0.2.9" }
httparse = "1.8.0"
hyper = { version = "1.6.0", features = ["full"] }
hyper-rustls = { version = "0.27.2", default-features = false, features = ["http1", "http2", "tls12", "aws-lc-rs"] }
hyper-util = { version = "0.1.10", features = ["tokio", "client", "client-legacy", "server", "server-auto"] }

Platform

Description
Hitting an error in Deno's fetch implementation when trying to access https://www.rd.usda.gov/sites/default/files/pdf-sample_0.pdf (denoland/deno#29951). I haven't yet fully debugged it yet, but the error returned is:

error sending request from 192.168.1.137:50655 for https://www.rd.usda.gov/sites/default/files/pdf-sample_0.pdf (23.192.87.138:443): client error (SendRequest): http2 error: stream error received: unexpected internal error encountered

which suggests this is coming deep from hyper stack

That it's "received" instead of "detected", that means the server sent a RST_STREAM of INTERNAL_ERROR (https://github.com/hyperium/h2/blob/6b27688442aed1200f436190bc54fad805f0b770/src/frame/reason.rs#L67). The server handler is probably throwing an exception or hitting a timeout (depends on the server framework, but for instance those are cases where Golang will return that reset code).

Thanks for the insight, funny enough visiting this website using a browser works fine. I'll try with reqwest and hyper itself.

It could be that something that is sent is making the server reset. 🤔
