how to check failure of a command in github action

I integrate STM32CubeProgrammer with github action for deploy.

Although the command exit with error, github action workflow did not fail so that the result is success.

Because the command print "Error" at console log, I just want to grep this and make the workflow fail. how can I do that?

I am using self-hosted runner(Windows 10)

jobs:
  build:...
    
  deployment:
    # The type of runner that the job will run on
    runs-on: [ self-hosted, deploy ]
    needs: build
    environment: production

    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:
      # Runs a set of commands using the runners shell
      - name: deploy
        run: |
          STM32_Programmer_CLI.exe -c port=SWD -w ${{ secrets.ELF_FILE }} ${{ secrets.START_ADDR }}
      
      - name: start
        run: |
          STM32_Programmer_CLI.exe -c port=SWD -c port=SWD -s ${{ secrets.START_ADDR }}

I save the output and use regular expression using -match

jobs:
  build:...
    
  deployment:
    # The type of runner that the job will run on
    runs-on: [ self-hosted, deploy ]
    needs: build
    environment: production
    outputs:
      result: ${{ steps.deploy.outputs.DEPLOY_RESULT }}

    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:
      - name: deploy
        # based on Windows Powershell batch script language
        run: |
          $deploy_result = $(STM32_Programmer_CLI.exe -c port=SWD -w ${{ env.ELF_FILE }} ${{ env.START_ADDR }})
          echo $deploy_result
          if ( $deploy_result -match "File download complete" ) {} else { exit 1 }
