   // success
   }).catch(function (err) {
   // error

When you import using the ESM module format:

import { canvasToBlob } from 'blob-util'

Then you omit the blobUtil part when you call it. It's only when you include it as a script tag that it creates a global blobUtil object. Hope that helps!

Property 'imgSrcToDataURL' does not exist on type '{}'.

It sounds like the library wasn't imported properly. Sorry I can't help you more than that...
