Problem in creating a Yaml pipeline in azure Devops - yaml

Question

these are the error that I can't fix image
trigger:
- master
schedules:
- cron: "0 17 * * * 6"
displayName: ogni giorno alle 17
branches:
include:
- master
always: false
pool:
vmImage: 'windows-2019'
variables:
buildConfiguration: 'Release'
parameters:
RestoreBuildProjects: '**/*.csproj'
steps:
- task: DotNetCoreCLI#2
displayName: 'Install .NET Core SDK'
inputs:
version: 5.0.x
performMultiLevelLookup: true
- task: DotNetCoreCLI#2
displayName: Restore
inputs:
command: 'restore'
projects: '$(Parameters.RestoreBuildProjects)'
vstsFeed:'f52d4c22-658b-47a0-a62f-134d5435cc85'
- task: DotNetCoreCLI#2
displayName: Build
inputs:
command: 'build'
projects: '**/*.csproj'
arguments: '--configuration $(buildConfiguration)'
- task: DotNetCoreCLI#2
displayName: Publish
inputs:
command: publish
publishWebProjects: True
arguments: '-c Release --output $(Build.ArtifactStagingDirectory)'
zipAfterPublish: True
- task: PublishBuildArtifacts#1
displayName: 'Publish Artifact'
inputs:
pathtoPublish: '$(Build.ArtifactStagingDirectory)'
artifactName: 'myWebsiteName'
I created this pipeline for an API ASP.NET Core based on the restful model but I can't make it work, as I try to run it it breaks, I've looked for the errors that Azuredevops gave me but I can't for any reason fix them. see attached email. Hope someone can help me. this is my first approach with YAML pipelines as I used to make them with the graphic tool integrated in Azure DevOPs.

I have helped to modify your yaml file and it shows no error on my test. Here is the yaml:
parameters:
- name: RestoreBuildProjects
type: string
default: '**/*.csproj'
trigger:
- master
schedules:
- cron: "0 17 * * * 6"
displayName: ogni giorno alle 17
branches:
include:
- master
always: false
pool:
vmImage: 'windows-2019'
variables:
buildConfiguration: 'Release'
steps:
- task: UseDotNet#2
inputs:
packageType: 'sdk'
version: '5.0.X'
performMultiLevelLookup: true
- task: DotNetCoreCLI#2
displayName: Restore
inputs:
command: 'restore'
projects: '$(Parameters.RestoreBuildProjects)'
feedsToUse: 'select'
# vstsFeed:'f52d4c22-658b-47a0-a62f-134d5435cc85'
- task: DotNetCoreCLI#2
displayName: Build
inputs:
command: 'build'
projects: '**/*.csproj'
arguments: '--configuration $(buildConfiguration)'
- task: DotNetCoreCLI#2
displayName: Publish
inputs:
command: publish
publishWebProjects: True
arguments: '-c Release --output $(Build.ArtifactStagingDirectory)'
zipAfterPublish: True
- task: PublishBuildArtifacts#1
displayName: 'Publish Artifact'
inputs:
pathtoPublish: '$(Build.ArtifactStagingDirectory)'
artifactName: 'myWebsiteName'
And please follow this step to use the yaml:
Create a new pipeline with the yaml edit.
Select the 'Starter Pipeline', this will help you create a new yaml file.
Copy the script to the pipeline.
Click the 'settings' on your restore task and select the feed you want to use. Then click the Add button. This step will help you input the full feed ID.
