.preload not defined

[cassiopagnoncelli]

Just included the gem into the bundle, installed it as per README instructions, and enabled it at class Schema.

Thing is, when I add preload to a type field, as in

Types::CustomerType = GraphQL::ObjectType.define do
  ...
  field :payments, !types[Types::PaymentType], preload: :payments
end

Error is as cumbersome as it gets:

GraphQL::Field can't define 'preload' excluded from capture: DSN not set

Using ruby-2.5.0 and rails-5.2.2. Ps: I think it is somewhat different from the other open issue as the error occurs at ObjectType level.

Can anyone shed a light here?

I guess it's just a syntax error. preload: :... need to be called in a block.

Types::CustomerType = GraphQL::ObjectType.define do
  ...
  field :payments, !types[Types::PaymentType] do
    preload: :payments
  end
end

and if you're using the old block syntax, preload is a function. so its preload :payments and NOT preload: payments

Solved with a resolver,

field :payments, [Types::PaymentType], null: false, resolver: Resolvers::AssocCustomerPayments

simpler and (I hope) more stable syntax.
