While running a wasm file facing the below error wbindgen_placeholder__ not found

Error: Service(Client(Execution(RuntimeConstruction(Instantiation("Instantiation: Module wbindgen_placeholder not found")))))

Wasm-bindgen only works when you are running inside the browser. When using a standalone wasm runtime you can't use it. You could try witx-bindgen instead. Which wasm runtime do you use by the way?

I am using substrate-wasm-builder = '4.0.0'
