Hi there,
I'm new to Scout and am currently trying to build a simple example based on the HelloScout example using IntelliJ as IDE in Win10.
I added a page with a list displaying some object data. Both server and ui started, so far so good.
Then I added a RestClient to get the data from a remote source and when I try to start the UI-Server, I now run into a very strange exception:

I have seen similar Stacks here in the forum, but yet could make not heads or tails out of it, especially since I fail to see a connection between the changes I made and the sudden appearance of the error... Any suggestions?
Kind regards,
Christian

Hi Mat,
thanks for the quick reply.
"1. Which JRE version do you use to start the application?" -> openJDK 17.0.1
"2. Which Scout version do you use?" -> 11.0.42
"3. What are the values of the properties "scout.auth.privateKey" and "scout.auth.publicKey" in your config.properties files?" -> they where both "changeme"/ the default since the helloworld-tutorial did not include instructions to change them. Or I missed those.
However, in the meantime I have been able to run the SecurityUtility and now have set the keys to the generated value and with that I was able to get the app running again. I still don't get though why this became an issue at all when all I changed was adding some new classes on the client side.
