• select a folder/package below the top level, or the 1st level ( e.g. src/main )
• Select New->Vaadin10+ Design
• Encounter attached error screen
• If you select any folder/package other than the top level, or 1 level deep, you get an error on the initial creation page (attached screenshot)
• for reference, attached a shot of my current directory structure

IDE, Designer and OS versi

• IDEA (2022.2.2), Designer (4.6.20), RHEL 8.7

The workaround to this issue should be to launch the application once. This will run "npm install" and load the dependencies like Polymer. The error message is misleading nowadays as with Vaadin 23 and 24 WebJAR's and Bower are not being used anymore. Also Vaadin 14 uses Node and npm (pnpm) by default.

Hi, did you manage to fix it? I Have this problem with Vaadin 24

With new Vaadin 24 versions you need to disable the pre-compiled frontend bundle
