Kindly see if there's need for an update to this library.

I am getting an error 400 while trying to create a subaccount.

sa, err := r.Paystack.SubAccount.Create(&paystack.SubAccount{
			BusinessName:        *data.Name,
			SettlementBank:      *data.Bank,
			AccountNumber:       *data.AccountNumber,
			PercentageCharge:    PercentageCharge,
			SettlementSchedule:  SettlementSchedule,
			PrimaryContactEmail: *data.Email,
			Metadata:            metadata,
		})

if err != nil {
    return nil, err
}
