Whitelabel Error Page

I cloned Kafdrop and packaged and ran as written in the readme. Kafdrop starts but when I click on a topic, I get: Whitelabel Error Page.
For example:

  1. If I hit localhost:9000, I can see Kafdrop running and list of all my topics and brokers.
  2. Click on a topic
  3. It shows Whitelabel Error Page (exception is thrown in background)
  4. If I manually append messages in URL: localhost:9000/topic/topic_name/messages, then I can see the messages page, but I'm missing on the page that describes the topic.

EDIT:

  • Formatting
  • URL corrected.
  • Improved question

What version of Kafka are you running?

Kafka: 0.10.0

ekoutanov commented

There is no real development taking place on Kafdrop 2.x. Consider updating to the next major version – Kafdrop 3.
