salaryBasisLov API REST is not returning salaryBasisComponents child collection

Summary:

I have a salary Basis that is set up as based in Components (see p1.jpg).

If I query this Salary Basis through the API rest salaryBasisLov

{{HCM_BNCR_HOST}}/hcmRestApi/resources/11.13.18.05/salaryBasisLov?expand=salaryBasisComponents&q=SalaryBasisId=300001885889790

I get the header data. But I don't get any data on the child collection salaryBasisComponents (see p2.jpg).

If I query the same SalaBasis in this way

{{HCM_BNCR_HOST}}/hcmRestApi/resources/11.13.18.05/salaryBasisLov/300001885889790/child/salaryBasisComponents

I get error 404 (see p3.jpg)

Is this a permission issue? Why I'm not able to get the child collection salaryBasisComponents??? 

Has anyone had this issue?
