Usage of pro components with Student subscription

Hi. I have a valid Student subscription and have been successfully using pro components to expedite my master’s project. After a few months without executing it, now I got the following error due to the licence for Vaadin CRUD and Map components:

The provided license key does not allow usage of vaadin-crud 24.3.10. Check that the license has not expired and that the product you are trying to use does not require another type of subscription. Component: vaadin-crud 24.3.10

Please find my pom.xml file below. It was created from Create a new Vaadin app: configure views and theme.

Am I missing something?

Thank you!

Hey Alex,

are you sure, you’re still participating in the GitHub student program? I can see that your student license at Vaadin expired. This means you will have to reverify yourself via https://vaadin.com/student-program

Then, it should work again. What bugs me is that you’re getting “all green” from the license validation view. It should have told you that your license is no longer valid.

Cheers,
Paul

Hi Paul,

Yes, I am participating in the GitHub Studen program. I tried to reverify and got the following message:
“Hi, Alex! You were last verified as a student on Apr 6, 2024. It is not necessary for you to reverify at this time.”

After login via https://vaadin.com/student-program , I see:
“Hey! You are already a member of the Vaadin Student Developer program”.

Finally, in my account subscriptions, I get the following message: “You have an active student subscription.”

I hope that helps to evaluate the issue.

Regards,
Alex

I can see your Vaadin Student license is active again. Can you confirm that everthing works as expected again?

And yes, your comments helped me to find a bug in the student license validation mechanism. I fixed it in the meantime so that others will not fail for it.

Thanks for that!

Hi Paul. Everything works as expected now. Thank you for your support :smiley:
