SNMP_exporter not providing tags from lookups

Exporters and Metrics
1

I’m not getting any errors, just a couple of empty tags.
I assume my config is wrong, but I have verified all snmp oid strings manually.
It pulls the main metric, but not the lookups to create the tags.

Output page of exporter

# HELP internal_sensor The temperature reading in Fahrenheit of the Internal Sensor
# TYPE internal_sensor gauge
internal_sensor{name="",type=""} 7687

Config of exporter

auths:
  public_v1:
    community: public
    security_level: noAuthNoPriv
    auth_protocol: MD5
    priv_protocol: DES
    version: 1
modules:

    timeout: 10s
    get:
    - 1.3.6.1.4.1.20916.1.9.1.1.1.2.0 # Metric
    - 1.3.6.1.4.1.20916.1.9.1.1.1.3.0 # Device Name
    - 1.3.6.1.2.1.1.5.0 # Device Type
    metrics:
    - name: internal_sensor
      oid: 1.3.6.1.4.1.20916.1.9.1.1.1.2.0
      type: gauge
      help: The temperature reading in Fahrenheit of the Internal Sensor
      lookups:
      - labels:
        - name
        labelname: name
        oid: 1.3.6.1.4.1.20916.1.9.1.1.1.3.0
        type: DisplayString
      - labels:

        labelname: type
        oid: 1.3.6.1.2.1.1.5.0
        type: DisplayString

Proof that at least name should work:

$ snmpget -v1 -c public 172.16.0.21 1.3.6.1.4.1.20916.1.9.1.1.1.3.0
iso.3.6.1.4.1.20916.1.9.1.1.1.3.0 = STRING: "Rack Sensor"

Anyone see what I’m doing wrong?
