In VS Code, I noticed that sometimes, it seems to indicate available code actions to convert a Promise.then() function to async/await with the three grey dots but then, when actually trying to execute the Quick Fix, it shows "No code actions available".

From my investigation, this seems to happen because one of the Promises inside the function has an any type.
I've found the current behavior really confusing because the combination of the three grey dots and then an unavailable Quick Fix is a strange combination.

TypeScript Version: 3.6.0-dev.20190808
Search Terms: code action async await promise
Code

let somePromise;
function myFunction() { // VS Code shows three grey dots and "This may be converted to an async function.ts(80006)" on hover
  return Promise.resolve()
  .then(() => {
    return somePromise
    .then(() => {
      return 'Yeah!';
    });
  });
}

Expected behavior:

Either:

• VS Code doesn't indicate an available code action in the first place
• It provides some kind of hint why it can't execute a quick fix or how to enable it
• The code action still works and does the conversion anyway
  Actual behavior:

VS Code shows a possible available code action but then there is none
