We are seeing customers occasionally get this issue. We are using WebViewer in our react codebase and when the customer tries to load a PDF file, it breaks. I’ve attached a screenshot of the console errors. We are seeing this across a few different customers a day.
Based on the console error, it seems the WebViewer lib dependencies are not loading correctly. Are you able to share the network tab when this issue occurs? A HAR capture could also help pinpoint why the issue is happening.
