A workflow cannot use recursion RRS feed

  • Question

  • I have this code in my module (psm1). The code works - that is not the issue.

    Workflow Test-WFConnection {
        # Run multiple parallel "pings" so it runs quicker
      foreach -parallel ($computer in $computers) {
            Computer = $computer
            Reachable = (Test-Connection -ComputerName $computer -Count 1 -Quiet)

    Since I installed WMF 5.x I get the error 'A workflow cannot use recursion' when I do the import-module cmdlet.

    Before WMF 5.x this exact code did not generate that error.

    Does anyone know what has changed?

  • Works fine for me.  Perhaps your module is not built correctly.

  • Thanks Joe.

    The code is in exactly the same place in the module as its always been.

    The module contains this workflow and a bucketload of functions.

  • No way to know the answer.  You will have to debug the module.

  • hmm I removed the workflow code above from the psm1 file and the error disappears.

  • Are you trying to call the workflow from within the module?

    You might just be facing a bug.

  • no - not calling the workflow from within the module. Its a bug...

  • Create a module with only the workflow and add back one function at a time.  It may just be a conflict.
