HasManyThrough - I can't get the main model's ID to load

[derianmarchan]

Laravel: 10
PHP: 8.1

HasManyThrough It doesn't load the ID of the model.

These are my models: Provider, ProviderProduct and QuotationMaterialProvider

This is my relationship:

It's logical that I want to reach the model QuotationMaterialProvider and load its data.
But the ID of the records isn't related to that model (QuotationMaterialProvider), but rather to the ProviderProduct apparently..

I was inspecting the data and the result is a combination of both Models/tables, but the ID of the main model doesn't load; an ID does appear, but it's from the intermediate model (ProviderProduct). Do I need to configure something additional?

LOAD DATA:

DATABASE ITEM

What should I do? Are the attributes being overwritten when the data is combined? I appreciate your help
