You can accomplish this by either updating this binary or the wasm-bindgen dependency in the Rust project. You should be able to update the wasm-bindgen dependency with: cargo update -p wasm-bindgen --precise 0.2.108 don't forget to recompile your Wasm file! Alternatively, you can update the binary with: cargo install -f wasm-bindgen-cli --version 0.2.127 if this warning fails to go away though and you're not sure what to do feel free to open an issue at https://github.com/wasm-bindgen/wasm-bindgen/issues!
