[Gladiator0619]

Hello guys,
I am trying to deploy RocketChat on kubernetes using Helm and pointing values.yaml file but its throwing error.

helm install rocketchat rocketchat/rocketchat -f values-microservices.yaml -n rocketchattest
Error: INSTALLATION FAILED: template: rocketchat/templates/secret.yaml:25:16: executing "rocketchat/templates/secret.yaml" at <include "rocketchat.mongodb.url" .>: error calling include: template: rocketchat/templates/_helpers.tpl:77:82: executing "rocketchat.mongodb.url" at <first .Values.mongodb.auth.passwords>: error calling first: runtime error: invalid memory address or nil pointer dereference

I have 3 replicas of mongodb working properly. My values file is mentioned below
