Apache NiFi Processor Configure -nifi-api redirect issue

[#1]

Apache NiFi Processor Configure issue,

Apache NiFi Kubernetes service installed and its running on Cluster Node. The Ingress, Kongingress and services are created for accessing the NiFi service outside of the cluster. NiFi service is accessible with this url:  http://<DNS-Host>/nifi/

Deployment-nifi.yaml

Ingress-nifi.yaml

Service-nifi.yaml

Apache NiFi Dashboard UI

When we configure the processor, the redirection is happening for processors and not able to open the configuration part. We are able to open some of the processor options like status history, view usage, change color, data provenance etc. But configure, delete requests are redirecting to /nifi-api with the URL adding 8000 ports.

http://<DNS-Host>:8000/nifi-api/processors/24f25eb5-016d-1000-fb0b-78e825958bde

Apache NiFi runs on 8080 ports but the nifi-api request using 8000 ports, and this message shows in the NiFi dashboard when requested the configure, delete api call.

Unable to communicate with NiFi

Please ensure the application is running and check the logs for any errors.  

Need support to fix this port where and how its configured.
