##[error]TypeError: Cannot read property 'split' of undefined

Getting the above error when trying to update a custom field value. using the below configuration:

- task: WorkItemUpdater@2
  inputs:
    workitemsSource: 'Build'
    workitemLimit: '999'
    updateAssignedTo: 'Never'
    updateFields: 'Microsoft.VSTS.Build.IntegrationBuild,Test Build'

Can you also post a logfile? Maybe run with debug enabled? I tested this functionality and it works, so it's probably a configuration/setup issue in your DevOps project.

Sorry for the delay. Things got crazy around the holidays.

Here is the raw log from the build. This is cloud DevOps, not on-prem:

I also was having this error. The workItemType field seems to be mandatory. Maybe a little validation / informative error message would make this a little easier to work through.

The workItemType is mandatory, if you use the classic YAML editor you w7ill see that this rule is enforced.
