KeyError, key not found

[maxtechera]

I'm using the base example with RecordLoader, like this in a resolver
Loaders::RecordLoader.for(Product).load(Product.ids)

I'm getting this error:
KeyError (key not found: 6)

6 is the first id loaded. I think its somehow related to promise_for(load_key) in loader.rb.

Has anyone had this happen?

That happens when Loaders::RecordLoader#perform calls fulfill with a key that wasn't among the keys passed into perform.

The problem is that you are passing an array of ids in as a single key, which it doesn't find using the id of a single record. Instead use Loaders::RecordLoader.for(Product).load_many(Product.ids)
