How to registerCompletionItemProvider (and avoid duplicates)?

nevermind, answered my own question. registerCompletionItemProvider returns an IDisposable with the dispose method which I can call on unmount

Hello @nickav , I ran into the same issue about registerCompletionItemProvider creating duplicates of my suggestions. However, I tried saving the IDisposable into a variable and using dispose() on unmount, without success.

Here is my code :

const [completionDisposable, setCompletionDisposable] = useState({});

  useEffect(
    () => () => {
      completionDisposable.dispose();
    },
    [],
  );

  const editorWillMount = (monaco: any) => {
    setMonacoObject(monaco);
    setCompletionDisposable(
      monaco.languages.registerCompletionItemProvider('vb', {
        provideCompletionItems() {
          return {
            suggestions: createAutoComplete(parameterList),
          };
        },
      }),
    );
  };

I get an error TypeError: completionDisposable.dispose is not a function anytime I leave the page.

Do you remember how you managed to dispose of the completionItemProvider ? Thanks in advance
