Get `Sum of` from two different join(Includes) in Sequelize - mysql

Question

I want to get sum of column from two different tables in sequilize.
I want to accurate totalpaid, refunded & refundable field, which vary according to group by, I'm not be able to resolve it.
//Some pre-desined variables
var totalPaidQueryStr = '(CASE WHEN (SUM(inv_payment_record_invoices.payment)) IS NULL THEN 0 ELSE (SUM(inv_payment_record_invoices.payment)) END)';
var totalPaidQuery = [Sequelize.literal(totalPaidQueryStr), 'totalpaid']; //Get the total paid amount till date;
var refundedQueryStr = '(CASE WHEN (SUM(inv_payment_record_refunds.amount)) IS NULL THEN 0 ELSE (SUM(inv_payment_record_refunds.amount)) END)';
var refundedQuery = [Sequelize.literal(refundedQueryStr), 'refunded']; //Get the total paid amount till date
var refundableQueryStr = `(inv_payment_records.amount - (${totalPaidQueryStr} + ${refundedQueryStr}))`;
var refundableQuery = [Sequelize.literal(refundableQueryStr), 'refundable']; //Get the total due amount
return InvPaymentRecords.findOne({
attributes: [
'customer_id',
'amount',
'company_currency_id',
'exchange_rate',
totalPaidQuery, //Want to accurate sum
refundedQuery, //Want to accurate sum
refundableQuery
],
where: {
'id': payment_record_id,
'company_id': company_id
},
include: [
{
model: InvPaymentRecordInvoices,
require: false,
attributes: [],
},
{
model: InvPaymentRecordRefund,
require: false,
attributes: [],
}
],
group: [
//'inv_payment_records.id',
//'inv_payment_record_invoices.id',
//'inv_payment_record_refunds.id'
]
}).then(iprdata => {
return sequelize.Promise.resolve(iprdata);
}).catch(error => {
return sequelize.Promise.reject(error);
})
