The same thing happens when you run storage-add with an invalid argument:
application-test: 23:35:47 ERROR juju.worker.uniter.context cannot add storage: adding storage count for unit-test-0: storage "count" not found
application-test: 23:35:47 ERROR juju.worker.uniter resolver loop error: executing operation "run action 8": running action "juju-run": cannot add storage: adding storage count for unit-test-0: storage "count" not found
