Umbrella chart v2.6.0 installation fails with ingress pathType validation error

[saitejeswar1]

The umbrella chart v2.6.0 fails to install due to an ingress validation error from the nginx-ingress-controller admission webhook. The error occurs because certain ingresses use the regex path /(/|$)(.*) with pathType: Prefix, which is invalid. Regex paths must use pathType: ImplementationSpecific

Environment

• Kubernetes Version: v1.34.0 (minikube)
• Helm Version: (as available in system)
• Chart: tractusx-dev/umbrella v2.6.0
• nginx-ingress-controller: (with validation webhook enabled)

Steps to Reproduce

1. Add the tractusx-dev Helm repository
2. Attempt to install with minimal configuration:

   helm install -f docs/umbrella/minimal-values.yaml umbrella tractusx-dev/umbrella \
     --namespace umbrella \
     --version v2.6.0 \
     --create-namespace

Error: INSTALLATION FAILED: failed to create resource: admission webhook "validate.nginx.ingress.kubernetes.io" denied the request: ingress contains invalid paths: path /(/|$)(.*) cannot be used with pathType Prefix

Root Cause

Multiple components in the umbrella chart use the regex path pattern /(/|$)(.*) with pathType: Prefix:

1. digital-twin-registry (DTR) - dataprovider-dtr ingress
2. BPDM components:
   • bpdm-gate: /gate(/|$)(.*)
   • bpdm-pool: /pool(/|$)(.*)
   • bpdm-orchestrator: /orchestrator(/|$)(.*)

According to Kubernetes ingress specifications and nginx-ingress-controller validation, regex path patterns require pathType: ImplementationSpecific, not pathType: Prefix.

Attempted Workarounds

Attempted to override the pathType in docs/umbrella/minimal-values.yaml:

# For DTR
tx-data-provider:
  digital-twin-registry:
    registry:
      ingress:
        pathType: ImplementationSpecific

# For BPDM
bpdm:
  bpdm-gate:
    ingress:
      enabled: false  # or pathType override
  bpdm-pool:
    ingress:
      enabled: false
  bpdm-orchestrator:
    ingress:
      enabled: false

However, the pathType override does not appear to be respected by the subchart templates.

Is there any way to solve this issue? or any way that I can install industry core hub and make it work for a custom use case?
