Describe the bug (actual behavior)

I created a cluster with name a/b but when I click on ex. Brokers under its name on the left pane I get an empty page on the right.

Expected behavior

I expect I can access the brokers page as for any other cluster.

Your installation details

I run it as part of a docker compose, this is the relevant section:

  ui:
    container_name: ui
    image: provectuslabs/kafka-ui:master
    ports:
      - 8080:8080
    environment:
      DYNAMIC_CONFIG_ENABLED: 'true'

Steps to reproduce

• Start the docker image
• Configure a valid cluster, put a / in its name
• Wait until the cluster is accessed and shown on the left pane
• Try to access any page under its name group, es. Broker

I have cloned the code and found that there are a few classes missing. Which branch should I checkout to to have enough code to run local ?

Can reproduce at latest version (83b5a60) - accidentally put question mark in the name of a cluster in the UI - and now when trying to get stats from that cluster Kafka UI page straight up hangs.
Why wasn't that thought out in the first place?
