Can't configure mapping.docs with istio

[eremeevfd]

My cluster configuration:

• GKE v.1.22.6-gke.300
• Istio v.1.13
• Edge-stack chart v.7.3.2
  My mapping:

apiVersion: getambassador.io/v2
kind: Mapping
metadata:
  annotations:
    argocd.argoproj.io/tracking-id: dev-assessor-svc:getambassador.io/Mapping:services/dev-assessor-svc

The issue I'm encountering can be visible in these 2 log lines from edge-stack pod:

I tried to set url instead of path: path: http://assessor.services/service/assessor/openapi/ but my service just disappears from DevPortal, however I don't get any errors.
