Pleroma.Gun.ConnectionPool.Reclaimer: dialyzer error

lib/pleroma/gun/connection_pool/reclaimer.ex:12:call
The function call will not succeed.

:gen_server.start(Pleroma.Gun.ConnectionPool.Reclaimer, [], [
  {:name, {:via, Registry, {Pleroma.Gun.ConnectionPool, <<_::72>>}}},
  ...
])

will never return since the success typing is:
(atom(), any(), [
  {:debug, [:log | :statistics | :trace | {_, _}]}
  | {:hibernate_after, timeout()}
  | {:spawn_opt, [:link | :monitor | {_, _}]}
  | {:timeout, timeout()}
]) :: :ignore | {:error, _} | {:ok, pid() | {pid(), reference()}}

and the contract is
(Module :: module(), Args :: term(), Options :: [start_opt()]) :: start_ret()
