How do you set KUBECONFIG to connect to Azure Kubernetes service from github actions deployment? - kubernetes

Question

I am trying to setup a deployment pipeline to configure an Azure Kubernetes service from github actions. I have found steps on the github actions marketplace for configuring various steps however I cannot get any combination of them to work correctly. I keep getting errors saying
error loading config file
"/home/runner/work/_temp/kubeconfig_xxxx": yaml: did not find
expected key
or similar errors saying
error loading config file couldn't get version/kind; json parse error: json: cannot unmarshal array into Go value of type struct { APIVersion string json:"apiVersion,omitempty; Kind string json:\kind,omitempty\ }
depending on how I try to pass the kube_config from Terraform. If I run the same environment locally it works so I am assuming there is something wrong with how it is setup on github actions.
Here is my deployment file:
name: Deploy
on:
workflow_dispatch:

<redacted>

deploy:
name: Deploy
runs-on: ubuntu-18.04
env:

- uses: azure/k8s-set-context#v1
with:
method: kubeconfig
kubeconfig: "${{ env.XXX }}"
- name: Test
run: |
kubectl get pods -o wide
I have tried setting KUBECONFIG and getting pods in one step using bash and it also fails. Any ideas what I am missing? Thanks in advance!
