Current behavior

After the LiveServer instance runs for a while it outputs this error message:

Uncaught (in promise) Error: A listener indicated an asynchronous response by returning true, but the message channel closed before a response was received

Expected behavior

Not throwing any error while running normally.

For Tooling issues:

Others

This appears to be a Node or NPM package issue. Found it opened here: https://github.com/mozilla/webextension-polyfill/issues/130

You might be able to fix it by returning a dummy response.
