Git based WIKI File Updater - Cannot read property 'replace' of undefined

[BossJake]

Hi There,

I'm using the cross-platform extension and pairing it with Wiki File updater. I'm running this in Azure Pipeline. I'm not quite sure what this error means. Appreciate your help. Thanks!

Here's the template that I used.

Looks like the issue is you are passing in your release notes as a file, but the WIKI updater task is expecting it to be a string, so using the value of contents variable which is empty. Hence the error

I think you need to just make sure the WIKI updater's Data Is File variable is set to true. You pipeline should be something similar to the following

   - task: WikiUpdaterTask@1
      inputs:
        repo: 'https://@dev.azure.com///_git/.wiki'
        # the filename in the target WIKI
        filename: 'releasenotes.md'                    
        replaceFile: True
        # the soure filename
        sourceFile: '$(Build.ArtifactStagingDirectory)\releasenotes.md' 
        dataIsFile: True
        message: 'Added release notes for build $(Build.BuildNumber)'
        localpath: '$(System.DefaultWorkingDirectory)\repo'
        useAgentToken: true
