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 Christian
Glad that you could make it work. Probably this was always an issue as creating new classes on the client side has nothing to do with that.
Please note that Scout 11 does not officially support Java 17 yet. This has never been tested! To be on the safe side I recommend using Java 11 instead.
Basically you should not need to change these values manually as they should be generated together with the project. Maybe these values are not generated because you use Java 17 (which is not supported). When using Java 11 you should get valid values for these properties out of the box.
Kind regards
Mat
