Azure Container app deploy container to existing app not working

Hi

I am trying to use AzureContainerApps task as mentioned on https://learn.microsoft.com/en-us/azure/container-apps/azure-pipelines to deploy a new container image in the existing container app. But got the error "Error: Unable to create Container App Environment."

We are using a self-hosted Linux agent. Below is YAML

```
steps:
- task: AzureContainerApps@0
displayName: 'Azure Container Apps Deploy'
inputs:
azureSubscription: 'OUR_SUBSCRIPTION'
imageToDeploy: 'XXX.azurecr.io/rlb-pulse-api/:$(Build.BuildId)'
containerAppName: 'conatainer_app_name'
resourceGroup: 'resource_group_name'
disableTelemetry: false

```

We are not creating a new environment, not sure why this task tries to create an environment. However, as per the logs it seems that it it getting wrong location of the resource group. Our current resource group is in Australiaeast instead of westus.

```

2023-05-26T06:52:29.3898822Z "West US 2"
```
