[question] reqwest requires curl to work??

[aaron-tillekeratne]

Hey reqwest team,

I'm building a debian:bookworm-slim image for a rust grpc api. Part of the server side of this API makes a http call to another service. But it looks like it fails with a rather unhelpful error message error sending request for url .

Doing some testing I noticed that it works fine if I install curl on the image.

Am I missing something here or is this a requirement for reqwest to make http requests?

Cheers,
A

Snippet of build

FROM debian:bookworm-slim AS release-base 

RUN apt-get update && apt-get upgrade -y  && apt-get install openssl -y
# binary copy and app stuff later

For the error, you can use the {:?} format, or use an error reporter, to be able to print the source chain, which will explain more what happened.

As for why it suddenly works with curl, perhaps the curl package includes a system dependency on a TLS package that reqwest also wants? Or that enables more features in one? Hard to know without the full error message.
