Describe the bug (actual behavior)

Hi Team,

I have deployed the Kafka UI 1.5.0 and getting 431 error when accessing it:

ARN [reactor-http-epoll-4[] r.n.h.s.HttpServerOperations: [3da8ead7, L:/10.1.27.171:8080 - R:/127.0.0.6:53035] Decoding failed: REQUEST(decodeResult: failure(io.netty.handler.codec.http.TooLongHttpHeaderException: HTTP header is larger than 8192 bytes.), version: HTTP/1.1)

how to increase the header size for this?

Expected behavior

No response

Your installation details

App version 1.5.0

using default configuration

Steps to reproduce

• define the request authentication using istio
• define the authorization policy to allow the specific azure groups
• create the virtualservice in istio and try accessing it.

this works for some users but only one user is affected

Hi,

• I'm not sure which version you have installed. The latest release is 1.2.0—could you please confirm which version you're using?
• The message "HTTP header is larger than 8192 bytes." indicates that someone is sending a request to the Kafbat UI with HTTP headers exceeding the maximum allowed size.
  If you require support for larger headers, you can increase the limit by setting the following parameter (value is in bytes):

server.max-http-request-header-size=20000

Let me know if you need further assistance.

I had mentioned the chart version v1.5.0 which uses the latest 1.2.0 version and i have configured the request header size in application.yml and it works as expected and we can close this and Thanks for the support
