Vaadin 23 - upload file get error with PDF

Flow
1

Java 17. Vaadin 23.3.29. dev mode
When uploads PDF file (.pdf), then got error below. But if changes file extension from .pdf to .zip, then it works.

import com.vaadin.flow.component.upload.Upload; @Id("butImportDocInit") private Upload butImportDocInit; butImportDocInit.setMaxFiles(1); butImportDocInit.setAcceptedFileTypes(".zip, .ZIP, .7z, .7Z, .pdf, .PDF");

P/S:

  • change file extension to .7z also not working.
  • Vaadin version 23.3.28 works fine. so this issue only happens with Vaadin 23.3.29.

The problem wasn’t in 23.3.28, right? If not, you could also go back in the meantime
