Report

Keda Core: 2.17.2
Issue: while using Azure AD Workload Identity in Keda it receives an error error parsing azure Pipelines metadata: sources must contain at least one TokenCredential.
Config:

1. TriggerAuthentication:

apiVersion: keda.sh/v1alpha1
kind: TriggerAuthentication
metadata:
  name: azure-workload-identity
spec:
  podIdentity:
    provider: azure-workload
    identityId: xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx
    identityTenantId: xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx-xxxxxxxx

2. ScaledObject:

apiVersion: keda.sh/v1alpha1
kind: ScaledJob
metadata:
  name: shrijan-scaledjob
spec:
  jobTargetRef:
    parallelism: 1
    completions: 1
    activeDeadlineSeconds: 600
    backoffLimit: 0
    template:
      ... # describes the [job template](https://kubernetes.io/docs/concepts/workloads/controllers/job)
  triggers:
    - metadata:
        demands: demand1, demand2
        organizationURLFromEnv: AZP_URL
        poolName: my-pool
        requireAllDemands: "true"
      type: azure-pipelines
      authenticationRef:
        name: azure-workload-identity

Expected Behavior

ScaledJob must be in ready state with azure-workload-identity as authentication .

Actual Behavior

NAME                       MIN   MAX   READY   ACTIVE      PAUSED    TRIGGERS            AUTHENTICATIONS          AGE
shrijan-scaledjob    0        40       False     Unknown   Unknown   azure-pipelines   azure-workload-identity   1s

Steps to Reproduce the Problem

1. Create a TriggerAuthentication with podIdentity referencing the Azure AD Workload Identity.
2. Create a ScaledJob referencing the above TriggerAuthentication in its authenticationRef.
