Azure DevOps error when trying to execute a task using an array - azure-devops

Question

I have an AZD deploy template as below. I am trying to execute a task (Kubernetes#1) multiple times looping an array that is defined in parameters.
parameters:
- name: env
- name: serviceConnection
- name: 'serviceNames'
type: object
default:
- audit
- export
- admin
jobs:
- deployment: Deployment
displayName: Deploy to ${{ parameters.env }}
environment: ${{ parameters.env }}
pool: on-prem-pool
variables:
- template: azure-deploy-vars.yaml
parameters:
env: ${{ parameters.env }}
timeoutInMinutes: 10
strategy:
runOnce:
deploy:
steps:
- script: |
echo "Prepare to deploy config for ${{ parameters.serviceNames}}. clean workspace"
ls -la
cd ..
ls -la
rm -rf config
rm -rf devops
rm -rf TestResults
rm -rf helm
rm -f config.sh
rm -f *.properties
displayName: 'Clean Workspace'
- checkout: config
path: config
- ${{ each service in parameters.serviceNames }}:
- task: Kubernetes#1
displayName: Deploy Config
inputs:
connectionType: Kubernetes Service Connection
kubernetesServiceEndpoint: '${{ parameters.serviceConnection }}'
namespace: '$(PROJECT_NAMESPACE)'
configMapName: '${{ service }}'
forceUpdateConfigMap: true
useConfigMapFile: true
configMapFile: '$(Agent.BuildDirectory)/config/${{ service }}/${{ parameters.env }}/application-${{ parameters.env }}.properties'
But I get this error when I try to run the pipeline.
Can anyone see point me if there is an error in my template?
Error:
/ci/azure-deploy.tpl.yaml: (Line: 41, Col: 11, Idx: 1048) - (Line: 41, Col: 12, Idx: 1049): While parsing a block mapping, did not find expected key.

You need to indent the line
- ${{ each service in parameters.serviceNames }}:
so that it matches the - script: and - checkout: lines above it, and then increases the indent of the following lines as well.
Corrected template:
parameters:
- name: env
- name: serviceConnection
- name: 'serviceNames'
type: object
default:
- audit
- export
- admin
jobs:
- deployment: Deployment
displayName: Deploy to ${{ parameters.env }}
environment: ${{ parameters.env }}
pool: on-prem-pool
variables:
- template: azure-deploy-vars.yaml
parameters:
env: ${{ parameters.env }}
timeoutInMinutes: 10
strategy:
runOnce:
deploy:
steps:
- script: |
echo "Prepare to deploy config for ${{ parameters.serviceNames}}. clean workspace"
ls -la
cd ..
ls -la
rm -rf config
rm -rf devops
rm -rf TestResults
rm -rf helm
rm -f config.sh
rm -f *.properties
displayName: 'Clean Workspace'
- checkout: config
path: config
- ${{ each service in parameters.serviceNames }}:
- task: Kubernetes#1
displayName: Deploy Config
inputs:
connectionType: Kubernetes Service Connection
kubernetesServiceEndpoint: '${{ parameters.serviceConnection }}'
namespace: '$(PROJECT_NAMESPACE)'
configMapName: '${{ service }}'
forceUpdateConfigMap: true
useConfigMapFile: true
configMapFile: '$(Agent.BuildDirectory)/config/${{ service }}/${{ parameters.env }}/application-${{ parameters.env }}.properties'
