vaadin-flow

Pro components in Vaadin development mode

I'm debugging a Vaadin Flow application using Pro Components (GridPro). I need to run the UI on my phone, to check usability on a mobile device. The application works, minus the pro components. Obviously, I have an active license (Vaadin subscription) and the components work if I run the application from https://localhost/

I get this error in the browser:

Internal error: no connection

Component: vaadin-grid-pro 24.3.10
Solution

  • I assume you are using a local IP to access your app on your phone. If so, have you tried adding it to vaadin.devmode.hostsAllowed?
