Research direction

Start from the model's expose declaration and the controller's nested parameter definition, then reproduce the reported array-of-hash request and inspect the type mismatch involving ActiveSupport::HashWithIndifferentAccess. Done means identifying why the declared Array[Hash] does not accept the received element and confirming the corrected behavior with a focused test or console reproduction.

Description

When I try to send an array of hash, I have the error instance of ActiveSupport::HashWithIndifferentAccess

Here is my model :
expose :book, documentation: { type: Array[Hash] }
And in my controller I have nested attributes like this :
requires :collection, type: Hash do optional :book, type: Array do requires :id, type: String requires :price, type: BigDecimal end end

When I check in my console the params book, I have an array with a hash :
[{"id"=>"351a7eaf-cf93-4f89-9f3a-b2cce4c07a70", "amount"=>0.23e2}]
But it returns the error Collection::book(#11898309) expected, got {"id"=>"351a7eaf-cf93-4f89-9f3a-b2cce4c07a70", "amount"=>0.23e2} which is an instance of ActiveSupport::HashWithIndifferentAccess(#510440)
Do you know what's wrong here ?
