Decorator skipping not working

can you please help me getting this decorator skipper fixed.
when i match the command line task from the decorator pipeline to the one in pipeline.yaml file. it is skipping, once i remove the command it is not working.

Please find the decorator.yaml and pipeline.yaml below.
steps:
- ${{ if ne(variables['skipInjecting'], 'true') }}:
- script: echo "$(variables['skipInjecting'])"
- bash: echo This is the Bash task
- task: PowerShell@2
inputs:
targetType: inline
script: echo "$(variables['skipInjecting'])"
- task: ADOSecurityScanner@1
inputs:
OrgName: '$(System.CollectionUri)'
ProjectNames: '$(System.TeamProject)'
ScanFilter: 'All'


trigger:
- master

pool:
vmImage: ubuntu-latest

variables:
skipInjecting: 'true'

steps:
- script: echo This is the only step. No decorator is added.

- script: echo Hello, world!
displayName: 'Run a one-line script'

- script: |
echo Add other tasks to build, test, and deploy your project.
echo See https://aka.ms/yaml
displayName: 'Run a multi-line script'

- task: CmdLine@2
task: PowerShell@2
inputs:
targetType: inline
script: echo "$(variables['skipInjecting'])"

can you please help in getting this fixed.
