Repro steps

The deployment seems to fail if I deploy it fast a second time. From time to time the very same configuration works...

steps:
- task: AzureContainerApps@1
  displayName: 'Azure Container Apps Deploy'
  inputs:
    azureSubscription: '***'
    imageToDeploy: 'myImage'
    containerAppName: 'myCOntainerName'
    resourceGroup: myRessourceGroup
    containerAppEnvironment: 'MyContainerAppENv'
    location: myLocation
    disableTelemetry: true
