Error installing GitLab Helm Chart on rancher (Invalid Semantic Version Check PostgreSQL Deprecated)

Hello

I’m trying to setup GitLab on rancher using the helm chart. Here is my values.yaml:

certmanager:
  install: false
global:
  ingress:
    configureCertmanager: false 
  gitlab:
    license: {}  
  gitaly:
    persistence:
      enabled: true
      #storageClass: <your-storage-class>
      accessModes: ["ReadWriteMany"]
      size: 1Ti
      #path: /srv/gitlab/data/gitaly
      existingClaim: pvc-gitlab
  hosts:
    domain: domain
  minio:    
    enabled: false    
  psql:
    host: server
    port: 5432
    username: gitlab
    password:
      secret: postgresql-secret
      key: password        
  smtp:
    address: smtp.mailgun.org
    authentication: plain
    enabled: false
    open_timeout: 30
    openssl_verify_mode: peer
    password:
      key: password
      secret: ''
    pool: false
    port: 2525
    read_timeout: 60
    starttls_auto: false
    user_name: ''  
  time_zone: America/Toronto  
nginx-ingress:
  enabled: false  
postgresql:  
  install: false

When i install on rancher using this values i got the following error:

Error: INSTALLATION FAILED: template: gitlab/templates/NOTES.txt:195:3: executing “gitlab/templates/NOTES.txt” at <include “gitlab.checkConfig” .>: error calling include: template: gitlab/templates/_checkConfig.tpl:70:34: executing “gitlab.checkConfig” at <include “gitlab.checkConfig.postgresql.deprecatedVersion” .>: error calling include: template: gitlab/templates/_checkConfig_postgresql.tpl:5:18: executing “gitlab.checkConfig.postgresql.deprecatedVersion” at <semver (.Values.postgresql.image.tag | toString)>: error calling semver: Invalid Semantic Version

I’m using an external PostgreSQL database.
Does any one knows how to fix this?

Thanks
