Not finding workflows to delete

[qd-danh]

Hello - really appreciate your custom action, just can't seem to get it to work.
Have tried both older-than-seconds (~1 month), and created-before (2022-01-01) options, so far with what-if set to true (want to make sure I have parameters correct before letting this thing loose)

and I definitely have older workflow runs (see screenshot)

Really two issues:

• not seeing any workflows listed that are found to delete
• seeing the warning about "Buffer() is deprecated" and not sure if that's related.
