Could not locate compiled WASM binary at `target/

Error message

Could not locate compiled WASM binary at `target/{target}/{PROFILE}/{wasm_name}.wasm` under configured target directory {}

What it means

Fired by locate_wasm_binary when `target/<target>/release/<wasm_name>.wasm` does not exist under the configured target directory. There is deliberately no recursive search: probing other roots could pick stale artifacts.

Solutions

1. Rebuild with the same target triple and target directory the build configures
2. Check that CARGO_TARGET_DIR/configured target dir matches where the build ran
3. Verify the wasm target component is installed and the build succeeded

When it happens
