EISDIR error when running migrate from Azure DevOps release pipeline

[mdecap]

I am trying to get this setup to run in a pipeline and receive the following error:

I also get a similar error to this when running the following Azure DevOps pipeline config:

trigger:
- main

pool:
  vmImage: windows-latest

steps:
- task: ineritedprocessmigration@1
  inputs:
    command: 'migrate'
    sourceAccount: 'source'
    sourceProcessName: 'Test'
    targetAccount: 'target'
    targetProcessName: 'Test'
    logFilename: 'output/processMigrator.log'

note: actual source and target account names have been replaced.

The error received is:
