Putting an array of marketplaceIds as a parameter for get_definitions_product_type and search_definitions_product_types isn't working

[Liritt]

Hello, I tried to put an array of marketplaceIds in the hope of having the data for all the marketplaces of the array but unfortunately it seems like putting an array of marktplaceids just return the data of the first element of the array.
For example, I tried with an array with Belgium and Germany but in the end it only returned the product types of Belgium and there isn't a "next token" or another page.
Is my way of using the api wrong or is it a bug ?
Thanks in advance for any response !
