YAML Implicit keys need to be on a single line, Implicit map keys need to be followed by map values

Question

trigger:
- develop

pool:
  vmImage: windows-2019

- task: MSBuild@1
  inputs:
    solution: '**/*.sln'
- task: DownloadBuildArtifacts@1
  inputs:
    buildType: 'current'
    downloadType: 'single'
    itemPattern: '**/*.exe'
    downloadPath: '$(System.ArtifactsDirectory)'

I get an error with this YAML in both Azure DevOps and using the YAML extension for VS Code. I'm trying to build a Windows Service and then put the .exe file somewhere that I can download it.

Azure DevOps: VSCode
