How can I do "Pipelines must be failed when services already started." in gitlab.ci yaml?

I have an gitlab ci yaml file. and 2 jobs.

my gitlab ci yaml file is:

 variables:
          MSBUILD_PATH: 'C:\Program Files (x86)\MSBuild\14.0\Bin\msbuild.exe'
          SOLUTION_PATH: 'Source/NewProject.sln'

        stages:
          - build
          - trigger_IT_service
          -

        build_job:
          stage: build
          script:
            - '& "$env:MSBUILD_PATH" "$env:SOLUTION_PATH" /nologo /t:Rebuild /p:Configuration=Debug'

        trigger_IT_service_job:
          stage: trigger_IT_service
          script:
            - 'curl http://webapps.xxx.com.tr/dataBus/runTransfer/ctDigiTransfer'


And It's my trigger_IT_service job report:

I have to control the this report "Content" part in gitlab ci yaml If "message" is "SAP transfer started. Please check in db" the pipeline should pass otherwise must be failed.

What I write "script" to control the Message in gitlab ci yaml. Thank you for all your helps.
