I am facing an issue with my web-client where it always throws an error "Function Import Requires a Callable". I have tried to resolve it by changing two different computers but it still persists. My web-client address is https://jerryokk.github.io/webtty/ and I have attached a screenshot for your reference (👇👇👇).

Can you please help me fix this issue?
