Usage of UseSourceLink results in 500 errors in Azure DevOps.

Describe the bug
When we enable <UseSourceLink>true</UseSourceLink> in our coverlet.runsettings file, Azure spits out errors like so:

For Generate Code Coverage:
2024-07-05T04:50:37: Error during reading file '[https://dev.azure.com/nztasd/SharedDelivery/_apis/git/repositories/Utilities/items?api-version=1.0&versionType=commit&version=8d856b2f1bd65c27e344fc86533a519f3a2f54fc&path=/Process/APIs/Services/BackgroundTasks/Workers/SendConfirmationEmailWorker.cs'](https://dev.azure.com/nztasd/SharedDelivery/_apis/git/repositories/Utilities/items?api-version=1.0&versionType=commit&version=8d856b2f1bd65c27e344fc86533a519f3a2f54fc&path=/Process/APIs/Services/BackgroundTasks/Workers/SendConfirmationEmailWorker.cs%27): Response status code does not indicate success: 500 (Internal Server Error).

To Reproduce
Turn on UseSourceLink in coverlet.settings, and use the following Pipeline build script:

- task: DotNetCoreCLI@2
    displayName: 'Run Tests'
    inputs:      
      projects: '${{parameters.solution}}'
      command: test
      arguments: '--configuration ${{parameters.buildConfiguration}} --no-build --collect:"XPlat Code Coverage" --settings coverlet.runsettings'

  - script: |
      dotnet tool install -g dotnet-reportgenerator-globaltool --add-source "https://api.nuget.org/v3/index.json" --ignore-failed-sources
      reportgenerator -reports:$(Agent.TempDirectory)\*\coverage.*.xml -targetdir:$(Build.SourcesDirectory)/CodeCoverage -reporttypes:"HtmlInline_AzurePipelines;Cobertura"
    displayName: Create code coverage report

  - task: PublishCodeCoverageResults@2
    displayName: Publish code coverage report
    condition: succeededOrFailed()
    inputs:
      codeCoverageTool: 'Cobertura'
      summaryFileLocation: '$(Build.SourcesDirectory)/CodeCoverage/Cobertura.xml'
      reportDirectory: '$(Build.SourcesDirectory)/CodeCoverage'
    env:
      DISABLE_COVERAGE_AUTOGENERATE: 'true'

Expected behavior
We're expecting source-links in the published report. As in, a direct link to the source file (in Azure's Git repository) that's being reported on.

Actual behavior
We're getting "source-links" that don't actually contain any links - as in, there's text saying https://dev.azure.com/.....SendConfirmationEmailRequest.cs but it's not actually a link.

Note that if we turn off UseSourceLink then the report contains a local file-path from the build agenet, e.g. D:\a\1\s\Experience\APIs\Controllers\VehiclesController.cs and we don't get any errors.

Configuration (please complete the following information):
Please provide more information on your .NET configuration:
* Coverlet version: 6.0.2
* .NET version: 8
* OS: WindowsLatest as specified by Azure build process.
* Architecture: x64

Additional context
There's what looks like a possible fix here, but I'd like to confirm that it's either a bug or that maybe we're doing something wrong. I've gone through the docs, but didn't see anything special related to Azure.

Cheers,

Matt.

Hi,
this looks like CI authentication issue and as far as I know coverlet does not handle any credentials.

Cheers, just wanted to double-check.
