Steps to Reproduce (for bugs)

.\Export-Permission.ps1

[IMJLA]

bug resolved in 0.0.176 which incorporates v0.0.63 of the Permission module

workaround implemented was to send a dummy object down the pipeline

closing bug, but adding new issue as enhancement to dig deeper into this behavior and implement a better solution

    # Bugfix #48 https://github.com/IMJLA/Export-Permission/issues/48
    # Sending a dummy object down the line to avoid errors
    # TODO: More elegant solution needed. Downstream code should be able to handle null input.
    # TODO: Why does this suppress errors, but the object never appears in the tables?
