Jbpm-server-full:7.61.0.Final AKS cannot open /business-central content path

[Sebastian ABC]

Hey JBPM community,

we installed jbpm-server-full:7.61.0.Final as a docker container in Azure Kubernetes Services with a KONG ingress controller. 

When we want to open https://server-name.com/<path>/business-central, we receive a 500 internal server error ( see attached file: global-jbpm-598957cd79-dj6xq-latest.log)

We got the following overall setup: 

Azure Frontdoor -> Kong Ingress Controller -> Kubernetes Service -> Kong Ingress defintion for JBPM -> JBPM pod.

When we do a port forwarding from the pod 8080 to local and test localhost:8080/business-central, then everthing works.

Do anybody know how to proceed with that topic?

Thanks in advance!
