Error excerpt:

File \"/tmp/ansible_purestorage.flasharray.purefa_pod_payload_dl6gq0tx/ansible_purestorage.flasharray.purefa_pod_payload.zip/ansible_collections/purestorage/flasharray/plugins/modules/purefa_pod.py\", line 631, in update_pod\nTypeError: object of type 'bool' has no len()\n"

To Reproduce Steps to reproduce the behavior:

1. Execute ansible-playbook task purefa_pod to promote active-dr pod. specify param undo: true
2. Response above.

Expected behavior Expect pod to be promoted as indicated.

Screenshots N/A

Additional context in purefa_pod.py, method get_undo_pod is called. the return values in get_undo_pod are cast as boolean. the returned value causes type error with len() as it expects what seems to be a list based on the logic present in update_pod method.
