Estou tentando passar de fase, Módulo Modelagem de dados, mas estou esbarrando na atividade Criar relacionamentos de objeto, onde após fazer o exercício e solicitando a validação do mesmo, sempre me responde com esta frase "o campo Property_c não existe

Hi @Marcio Souza ,

You need to check if somehow you missed field level security Click on the field and check field level security.

1. From Setup, open Object Manager, and then in the Quick Find box, enter the name of the object containing the field.
2. Select the object, and then click Fields & Relationships.
3. Select the field you want to modify.
4. Click Set Field-Level Security.
5. Specify the field's access level.
6. Save your changes.
