Tempo distributed helm chart failing to install with "unclosed action" after upgrading from 1.7.3 to 1.22.1

[danfinn]

I'm working on updating an out of date tempo deployment. I have not changed my values file, I'm using the same values that worked on 1.7.3. My values are:

      compactor:
        config:
          compaction:
            block_retention: 720h
      storage:
        trace:
          backend: azure
          azure:
            container_name: tempo
            storage_account_name: "{{ storage_account_name }}"
            storage_account_key: "{{ storage_account_keys_output.0.value }}"
      #MinIO storage configuration
      #minio:
      #  enabled: true
      #  mode: standalone
      #  rootUser: grafana-tempo
      #  rootPassword: supersecret
      #  buckets:
      #    # Default Tempo storage bucket
      #    - name: tempo-traces
      #      policy: none
      #      purge: false
      traces:
        otlp:
          grpc:
            enabled: true
          http:
            enabled: true
        zipkin:
          enabled: false
        jaeger:
          thriftHttp:
            enabled: false
        opencensus:
          enabled: false

Nothing in my values specifies anything about ingester and it seems I'm using pretty much the same values documented here (other than minio being commented out): https://grafana.com/docs/helm-charts/tempo-distributed/next/get-started-helm-charts/

but on install I'm getting the following error:

    "msg": "Failure when executing Helm command. Exited 1.\nstdout: Release \"tempo\" does not exist. Installing it now.\n\nstderr: Error: parse error at (tempo-distributed/templates/ingester/_helpers-ingester.tpl:16): unclosed action\n",
    "stderr": "Error: parse error at (tempo-distributed/templates/ingester/_helpers-ingester.tpl:16): unclosed action\n",
    "stderr_lines": [
        "Error: parse error at (tempo-distributed/templates/ingester/_helpers-ingester.tpl:16): unclosed action"
    ],
