I deploy it from chart versions 1.13.9 and 1.13.10 thought ArgoCD.

oncall-engine with same env successfully connected to rabbit, redis and postgres

How do we reproduce it?

1. try to install Chart version 1.13.9 or 1.13.10 with ArgoCD
2. Use that values for rabbitmq and redis

rabbitmq:
  enabled: true
  auth:
    existingPasswordSecret: "slackauth"

broker:
  type: rabbitmq

redis:
  enabled: true
  auth:
    existingSecret:

Grafana OnCall Version

v1.13.9, v1.13.10

Product Area

Helm/Kubernetes/Docker

Grafana OnCall Platform?

Kubernetes

User's Browser?

No response

Anything else to add?

No response

Also tried v1.13.3 - and it still same error.
I resolve it by removing value of key existingPasswordSecret:.
But now on every redeploy rabbitMQ lose itself credentials and key to resolve that problen - scale StatefulSet to zero, drop PVC and scale it back to one.
