Error with PublishSymbols Task in Azure DevOps - "RequestSealedException: Request is sealed. Only expirationDate may be modified."

Question

I am encountering an issue with the PublishSymbols task in my Azure DevOps pipeline. The exact error message I receive is as follows:

[Symbol App] Microsoft.VisualStudio.Services.Symbol.WebApi.RequestSealedException: Request ... is sealed. Only expirationDate may be modified.

The section of my pipeline configuration concerning the PublishSymbols task is as follows:

# Publish symbols for Windows builds
- task: PublishSymbols@2
  system.debug: true
  displayName: 'Publish symbols'
  inputs:
    SymbolsFolder: '$(Build.SourcesDirectory)/webrtc/native/src/out'
    SearchPattern: '**/webrtc.pdb'
    SymbolServerType: TeamServices
    SymbolsVersion: '$(WebrtcVersion)'
    SymbolsArtifactName: 'Symbols_WebRTC_$(BuildPlatform)_$(BuildSystem)'
  condition: and(eq(variables['BuildConfiguration'], 'Release'), in(variables['BuildSystem'], 'Windows'))

The error message implies that a request is sealed. However, I'm not sure what this means or how to resolve it.

Answer 1

It seems it's a bug in PublishSymbols@2 task. There are two workarounds for that:

1.Simply remove the SymbolsArtifactName field. Or

2.Make SymbolsArtifactName unique by appending _$(Build.BuildNumber) to its value.

  SymbolsArtifactName: 'Symbols_WebRTC_$(BuildPlatform)_$(BuildSystem)_$(Build.BuildNumber)'
