Playing a little with code looks like it doesn't like this piece of code:

  const
   {
        contextName = 'gl',
         throwGetError,
        useTrackablePrimitives,
        readPixelsFile,
        recording = [],
        variables = {},
        onReadPixels,
        onUnrecognizedArgumentLookup,
   } = options;

Thanks for this bug report. This is because of Destructuring Assignment with Default Values not implemented yet.
