Thanks for the pointer.
from inspecting the code it looks like drab run_handler() looks straightforward, with three required parameters, with the handler_function having arity 2. But I am getting an error (see simple example below). Probably something simple so thought I would ask.
from mix.exs
{:drab, “~> 0.5.6”},
commander handler example:
def test_handler(_first, _second) do
IO.puts(“hello form test_handler”)
end
from browser console:
Drab.run_handler(“test_event_name”, “test_handler”, {“answer”: 42})
The error from server:
ERROR:

Any advice appreciated. thanks.
