No package found with specified pattern in AzureRmWebAppDeployment#4 - azure-devops

Question

I have the following Azure Pipelines jobs:
- job: Publish
pool:
vmImage: 'Ubuntu 16.04'
steps:
- task: UseDotNet#2
displayName: Setup
inputs:
packageType: sdk
version: 3.1.x
- task: DotNetCoreCLI#2
displayName: Publish
inputs:
command: publish
publishWebProjects: false
projects: 'src/**/*.csproj'
arguments: '--configuration staging --output $(Build.ArtifactStagingDirectory)'
zipAfterPublish: true
- task: PublishPipelineArtifact#1
displayName: Export
inputs:
artifact: 'Staging'
targetPath: '$(Build.ArtifactStagingDirectory)'
- deployment: Deploy
dependsOn: Publish
pool:
vmImage: Ubuntu-16.04
environment: staging
strategy:
runOnce:
deploy:
steps:
- task: DownloadPipelineArtifact#2
displayName: Import
inputs:
artifact: 'Staging'
- task: AzureRmWebAppDeployment#4
displayName: Api
inputs:
connectedServiceName: '$(azure.subscription)'
webAppKind: 'webApp'
webAppName: 'bityond-demo-api'
package: '$(Build.ArtifactStagingDirectory)/Api.zip'
removeAdditionalFilesFlag: true
When I run the pipeline the following tasks are successful:
Setup
Publish
Export
Import
Then on the last task, "Api" - AzureRmWebAppDeployment#4, I get the error:
##[error]Error: No package found with specified pattern: /home/vsts/work/1/a/Api.zip<br/>Check if the package mentioned in the task is published as an artifact in the build or a previous stage and downloaded in the current job.
I checked and the artifacts are available and I am able to download them.
And the Import task is successful so what I am missing?

Answer 1

Try to specify destination directory for the imported artifact:
- task: DownloadPipelineArtifact#2
inputs:
artifact: 'Staging'
targetPath: '$(Build.ArtifactStagingDirectory)'
If not specified, artifacts by defaults are downloaded into $(Pipeline.Workspace) directory that is equal to /home/vsts/work/1. And for the AzureRmWebAppDeployment#4 task you are looking for artifacts at $(Build.ArtifactStagingDirectory) directory (equal to /home/vsts/work/1/a)
