Spector.js: Module Use Error: "No frames detected. Try moving the camera or implementing requestAnimationFrame."

I am trying to use the spectorjs module.

      const s = new SPECTOR.Spector();      
      s.displayUI(); 

This renders the Spector UI:

When I try to record I get the error.

No frames detected. Try moving the camera or implementing requestAnimationFrame. I definitely have requestAnimation frame running. The UI detects multiple canvas’s on the page. One of them being the correct webgl canvas.
