Mutex name not interpolated

[krisztiankocsis]

Hi!

We have this YAML (subset only):

apiVersion: argoproj.io/v1alpha1
kind: WorkflowTemplate
metadata:
  name: judge
  labels:
    app: judge
spec:
  entrypoint: judge
  workflowMetadata:
    labels:
      app: judge
  synchronization:
      mutexes:
      - name: "wf-judge-{{ '{{inputs.parameters.job_type}}' }}-{{ '{{inputs.parameters.job_class}}' }}"
  podGC:
    strategy: OnPodCompletion
  arguments:
    parameters:
      - name: job_type
        enum:
          - "ORDER_BASED_AAB_FILES"
          - "DEMAND_BASED_SDD_FILES"
          - "ORDER_BASED_KAFKA_MESSAGES"
          - "DEMAND_BASED_KAFKA_MESSAGES"
      - name: job_class
        enum:
          - "NORMAL"
          - "MTE"
          - "MIXED"
...

When I start this app with job_type = ORDER_BASED_AAB_FILES + job_class = NORMAL, I would expect that I can run an other in parallel with having job_type = DEMAND_BASED_SDD_FILES + job_class = NORMAL, but its blocking on the mutex:

Waiting for dev-4/Mutex/wf-judge-{{inputs.parameters.job_type}}-{{inputs.parameters.job_class}} lock. Lock status: 0/1

Seems that the mutex name is not resolved, not interpolated correcrtly.

Is this a bug or am I miss something or using it incorrectly?
We're using the latest version of Argo.
