Tenho um problema quando preciso retornar usando manipuladores de conclusão, mas solicito de 2 API Endpoints.

O primeiro endpoint é fetchSlideOnSale...

O segundo endpoint é fetchProducts

Informações adicionais: quando preciso buscar o primeiro ou o segundo endpoint, preciso primeiro do baseData

Não consigo retornar manipuladores de conclusão como o código abaixo. o problema do código da linha retorna esse erro

Não é possível converter o valor do tipo '[DaftarProdukItem]' para o tipo de argumento esperado '[OnSaleItem]'
