ReportGenerator 5.5.11 pipeline task error: crypto.randomUUID is not a function

[javizcaino]

Azure DevOps Server (on-prem) ReportGenerator task fails on execution due to node version selected is not correct.

Currently using
Azure DevOps Server 2022.2
Agent 4.265.0

ReportGenerator 5.5.11
azure-pipelines-task-lib 5.278.0

In Task.json we find this execution elements:
Node10
Node16
Node20_1
Node24

But runtime selected:
D:\AzureDevOpsAgent\externals\node\bin\node.exe (v6.17.1)

This result in error: crypto.randomUUID is not a function

Task log content is:

If ReportGenerator is executed as a .NET tool, it works correctly.

I would suggest that you use one of the other available options:

• https://www.nuget.org/packages/ReportGenerator
• https://www.nuget.org/packages/dotnet-reportgenerator-globaltool

I can't provide support for custom agents.

Isn't the Azure Pipelines Task developed by you? I believed that because of it being developed by you...

Microsoft AzureDevOps marketplace states this:

Isn't this yourself?

[danielpalme]

Yes, it's my extension.
I can only test the extension on Azure DevOps not on Azure DevOps Server (on-prem).

If you use the on-prem version of Azure DevOps, you are probably using a custom build agent.
I can't provide support for custom build agents since I can't control which tools are installed.
I can only test the images provided by Microsoft (ubuntu-latest and windows-latest).

You can try to install Node 24 on your build server (or in your pipeline) or just use one of the other options which don't require NodeJS.
The ReportGenerator task is just a simple wrapper around those.
