Craft GraphQL APIs in Elixir with Absinthe: trigger uses incorrect arity (page 118)
Page 118 contains the following trigger code:
trigger :ready_order, topic:
fn %{ ready: order}, _ -> [order.id]
_, _ -> []
end
The trigger function in the latest version of absinthe is 1-arity, using 2-arity will cause it to blow up with a cryptic error. The correct code is:
trigger :ready_order, topic:
fn %{ ready: order} -> [order.id]
_ -> []
end
