Hey there,

In the future please fully fill out the issue template so I do not have to ask the following questions:

Can you please provide me with sample code showing how you are loading the document? Also if you have a document that you can reproduce with, sending that over would be helpful as well.

Thanks,
Logan

hey Logan,
here is a code sample of how I am loading the document.

//first convert the base64 string to blob
// this.data is a base64 string 

const doc = fetch(this.data)
  .then(res => res.blob())
  .then(console.log)

//then load the document using the blob
instance.UI.loadDocument(doc, { filename: 'myfile.pdf' });

Hi there,

fetch returns a Promise that you are not waiting for - you need to await it or move your loadDocument call into the last then block.

Thanks!
Logan
