Using Vaadin 14.2.3 and changed from version 2.0.0 to 3.0.0 and this happens after login (not even trying to show a PDF):

I cannot reproduce the issue. I looks like this is not a problem with the pdf-browser component but with your build. Try removing the node_modules directory and building the app again. I cannot think of any other solution with what you shared.

Removed the node_modules directory. No joy, same results.

Unfortunately, there’s not much I can do without seeing the relevant code.

I put PdfBrowserViewer.java directly into our project. Compiles fine, however, I have to comment out @JsModule(“@lrnwebcomponents/pdf-browser-viewer/pdf-browser-viewer.js”) to prevent the above error.

Do you have any suggestions how to proceed?

I can take a look if you are able to provide a minimal runnable project to reproduce the issue.

Not necessary. Went with the solution provided by Dennis Reichenberg.
