Please help to find the issue

Answer 1

Trying to change the section Package to use the path from pathToPublish by default it was System.DefaultWorkingDirectory .

- task: PublishBuildArtifacts@1
  inputs:
    artifactName: 'drop'
    pathToPublish: '$(build.artifactStagingDirectory)'

Change in IISWebAppDeploymentOnMachineGroup task:

- task: IISWebAppDeploymentOnMachineGroup@0
  displayName: 'IIS Web App Deploy'
  inputs:
    WebSiteName: '$(Parameters.WebsiteName)'
    Package: '$(build.artifactStagingDirectory)/*.zip'
    RemoveAdditionalFilesFlag: true
    TakeAppOfflineFlag: true
    XmlVariableSubstitution: True

Build.ArtifactStagingDirectory :

The local path on the agent where any artifacts are copied to before being pushed to their destination. For example: c:\agent_work\1\a

System.DefaultWorkingDirectory:

The local path on the agent where your source code files are downloaded. For example: c:\agent_work\1\s

For this,please refer to predefined variables .
