Hi, I have a problem with webpack build within a multiplatform project. The frontend build fails with the following error:

Execution failed for task ':jsBrowserProductionWebpack'.
>                 Process 'webpack' returns 2

I've narrowed the problem down to the usage of io.ktor.client.HttpClient class. This error appears if I instantiate it or obtain its reflection descriptor in any part of the js source set and goes away if I remove all references of this class from the source set.
My Kotlin multiplatform plugin version is 1.3.71 and Ktor version is 1.3.2. I have dependencies on both io.ktor:ktor-client-core and io.ktor:ktor-client-js in my jsMain source set.
Any help is appreciated - maybe anyone has ideas on why this is happening or at least how to gain more insight into what is happening during the webpack build.

I was able to reproduce this problem in a smaller test project, and for some reason I've got a detailed output from webpack there. It turned out to be the same as described here https://github.com/ktorio/ktor/issues/961#issuecomment-602081220.

I was able to get rid of most of these errors by adding explicit npm dependencies for text-encoding, bufferutil, utf-8-validate and abort-controller. But one more error still remains and I don't know what to do about it:

ERROR in C:/Projects/Spike/build/js/node_modules/node-gyp-build/index.js

Sounds similar to what I was seeing here https://github.com/ktorio/ktor/issues/1724

Yep, looks the same. Looks like ktor http client just doesn't work with js target currently, so I'll look for alternatives

fs is module related with file system, and available only with usage in NodeJS environment
