helm chart issue PASSWORDS ERROR

[curly3031]

if we use default databases in chart and change clusterDomain from default "cluster.local", we have some error on non installed variables
example:
Error: UPGRADE FAILED: execution error at (oncall/charts/rabbitmq/templates/statefulset.yaml:37:28):
PASSWORDS ERROR: You must provide your current passwords when upgrading the release.
Note that even after reinstallation, old credentials may be needed as they may be kept in persistent volume claims.
Further information can be obtained at https://docs.bitnami.com/general/how-to/troubleshoot-helm-chart-issues/#credential-errors-while-upgrading-chart-releases

'auth.password' must not be empty, please add '--set auth.password=$RABBITMQ_PASSWORD' to the command. To get the current value:

    export RABBITMQ_PASSWORD=$(kubectl get secret --namespace "grafana-oncall" grafana-oncall-rabbitmq -o jsonpath="{.data.rabbitmq-password}" | base64 --decode)

in turn, setting this value does not work, because dependent charts are installed with priority while setting their own oncall
