InjectedIdentity provider config source is not working

[himanshu-josh1]

What happened?

I made an attempt to use InjectedIdentity as a source for ProviderConfig. As a test, I created an instance resource, but it triggered the subsequent event.

Warning  CannotConnectToProvider  3m38s (x25 over 3m52s)  managed/compute.gcp.jet.crossplane.io/v1alpha2, kind=instance  cannot get terraform setup: cannot extract credentials: no extraction handler registered for source: InjectedIdentity

How can we reproduce it?

Cluster has been setup to use Workload Identity using the below document
https://github.com/crossplane-contrib/provider-gcp/blob/master/docs/AUTHENTICATION.md

• Install crossplane [stable version]
• Install provider-jet-gcp package (Version: v0.2.0-preview)
• Adding credential source as InjectedIdentity in ProviderConfig

kind: ProviderConfig
metadata:
  name: default
spec:
  projectID: <<ProjectId>>
  credentials:
    source: InjectedIdentity

• Deploying Instance resource using provider-jet-gcp

apiVersion: compute.gcp.jet.crossplane.io/v1alpha2
kind: Instance
metadata:
  name: <<InstanceName>>
spec:
  providerConfigRef: 
    name: default
  forProvider:
    machineType: e2-medium
    zone: us-east4-c
    labels:
      managed-by: crossplane
    networkInterface:
      - network: <<NetworkName>>
        subnetwork: <<SubnetName>>
    bootDisk:
      - initializeParams:
          - image: debian-cloud/debian-9

What environment did it happen in?

Crossplane version:
Provider version:

• kubernetes version:
  Client Version: v1.23.4
  Server Version: v1.22.8-gke.202
• Kubernetes distribution : GKE
• Crossplane Installation:

helm repo add crossplane-stable https://charts.crossplane.io/stable  
helm install crossplane --create-namespace --namespace crossplane-system crossplane-stable/crossplane

• Provider version: crossplane/provider-jet-gcp:v0.2.0-preview

after some deep dive into to code, I have fixed by setting “None” as source for credentials

apiVersion: gcp.jet.crossplane.io/v1alpha1
kind: ProviderConfig
metadata:
  name: gcp-jet-provider
spec:
  projectID: XXXX
  credentials:
    source: None
