We need more information to look into this issue:
- Where are you seeing this error, your project or one of our samples? (an URL to the sample will help)
- What does the browser developer console log look like (what does the network tab looks like)
- Does this happen for every one of your documents or only a few. If it’s only happening for some document, would it be possible to get a copy of the document you uploaded that is causing this error.
