Unknown "airbyte_version" variable on airbyte-webapp

I deployed Airbyte via Helm (v0.45.12) using an external database, and all pods start successfully, except for airbyte-webapp, which is stuck in a crashloop. The logs show

/docker-entrypoint.sh: /docker-entrypoint.d/ is not empty, will attempt to perform configuration

nginx: [emerg] unknown "airbyte_version" variable

My chart value overrides are

  existingSecret: airbyte-db
  existingSecretPasswordKey: DB_PASSWORD
  host: XXXXXXX
  user: airbyte
    host: XXXXXXX
    secretName: airbyte-db
    secretValue: DB_PASSWORD
  enabled: false
    iam.gke.io/gcp-service-account: XXXXXXXXXXX

Same here, but on AWS

The solution was to use a different Helm chart version (I successfully deployed 0.45.11)
