When executing bin/garbage set-policy ... on my instance I get:
phabricator # ./bin/garbage set-policy --collector worker.tasks --days 3 [Invalid Translation!] The "en_US" language data offers variant translations for the plurality or gender of argument 1, but the value for that argument is not an integer, PhutilNumber, or PhutilPerson (it is a value of type "string"). Raw input: <Setting retention policy for "%s" to %s day(s).>. Wrote new policy to local configuration. This change will take effect the next time the daemons are restarted.
The command still succeeds and the policy gets updated.
