Supervisor : can't terminate a child by pid

Trying to terminate a child by its pid does not work, it should according to the documentation : https://hexdocs.pm/elixir/1.3.3/Supervisor.html#terminate_child/2

iex(7)> {:ok, sup} = Supervisor.start_link([], strategy: :one_for_one)                           
{:ok, #PID<0.383.0>}
iex(8)> {:ok, pid} = Supervisor.start_child(sup, worker(RData.ExpectedRefurbishmentCost, [self()]))
{:ok, #PID<0.385.0>}
iex(9)> Supervisor.terminate_child(sup, pid)                                                       
{:error, :not_found}

Any clues to make it work ?

You need to pass the child id to terminate_child for all strategies except :simple_one_for_one. So, for :one_for_one, the following should work for you since the id is set to the module by Supervisor.Spec.worker/3 if one is not provided:

Supervisor.terminate_child(sup, RData.ExpectedRefurbishmentCost)
