What does a double await mean in javascript?

Question

I was looking at some codebase and found this. Notice there are two await next to each other

 await  await fetch(fetchUrl, { method: 'get' , cache:"no-store" , headers: {
    'Cache-Control': 'no-cache'
  }})
     .then(res => res.blob())
     .then(res => {
        const data = window.URL.createObjectURL(res);
        var .................

Is it a bug? Or what is its meaning?
