Vaadin Whitelabel Error Page "Failed to install Node"

I am using the Vaadin sping boot web app starter and everytime I run the application java file to start the web page, I always get

There was an unexpected error (type=Internal Server Error, status=500). java.lang.IllegalStateException: Failed to install Node"

Followed by hundreds of lines of error messages all related to either node or zip END header not found. Even though I have Node.js installed on my Laptop. I'm using JDK 18, Windows 10, IntelliJ community edition 2022.1.2 and Vaadin 22. Any help on how to get my localhost up and running would be greatly appreciated.

Solution

  • Since you did not mention any build automation tool that you use, you can solve the problem by installing two missing tools (Node.js and npm) manually.

    1. Go to https://nodejs.org/en/download
    2. Choose and download installer
    3. Make sure npm is also installed (select the option)
