I'm getting an exception while running the UI.
Here's the code:
I just hit http://localhost:9000/ once after the port is opened & UI is started.
Selected the latest session where UI is running at the moment:

And I got these results:

Turns out you didn't actually include any code (looks like you intended to?)
I'm unable to reproduce this without some code (I tried a couple of things based on the stack trace, but everything runs fine for me)

Since it was giving me error, I removed those block of code to go ahead and execute my code with other changes. Here you can find actual code that has UI in it:

I still haven't been able to reproduce this. But looking at the stack trace again, the only thing this can be is a concurrent modification issue. I've implemented a check to avoid this here: #5947
