Nobody has claimed this yet.

## Repro

1. `cargo new surf-wasm-test --lib`
2. edit "Cargo.toml"
- `crate-type = [ "cdylib" ]` in `[lib]`
- `surf = { version = "2.3.2", fefault-features = false, features = [ "wasm-client" ] }` in `[dependencies]`
3. `cargo check --target wasm32-unknown-unknown`, and then it occur the error.

```

Reproduce the issue with the Cargo.toml settings from the report and run cargo check --target wasm32-unknown-unknown. Inspect surf-2.3.2/src/client.rs and the wasm-client feature configuration around the unresolved http_client::isahc import. Done means the provided wasm setup compiles without error.
