Can't make UI.loadDocument work when trying to load Blob

Product: WebViewer DOCX Editing

Product Version: Latest

Please give a brief summary of your issue: Can’t make UI.loadDocument work with Blob file.

Please describe your issue and provide steps to reproduce it:

I made a document using DOCX tool and then I saved it into a database. The thing is, when I trying to get the document from the server using the fetch() method, I can’t load the file using the UI.loadDocument(). . Bellow I show some images with little description that might help.

This image is when I convert the document to Blob to send it to the server

This image is when I get the file from the server.

Finally, here’s where I’m using the UI.loadDocument() based on the Blob file I get from server.

And here’s the result. Also, I don’t have any error message on the console… Just, not working.
