Nested order_by in sequelize - node.js

Question

I have to implement Nested orderby using sequelize but its not working below is my code
This whole code is working for me but I need to add sorting for a column reported_by which is present in Ticket table by reported_user_id name.
Below given images shows the hierarchy of database
TicketAssignment Table
Ticket Table
User table
TicketAssignment Table - ticket_id(FK) -> Ticket Table - id(PK)
Ticket Table - reported_user_id(FK) -> User Table - id(PK)
[let query = req.body.q;
let err, tickets;
let whereObj = {};
if (req.body.statusForTicket > 0) {
whereObj.status = 3;
} else {
whereObj.status = { [Op.in]: [0, 1, 2, 4, 5] };
}
if (req.user.role_id == 9) {
whereObj.suppport_company_id = req.user.company_id;
} else {
whereObj.engineer_user_id = req.user.id;
}
let whereObjInc = {};
if (query.trim() != "") {
whereObjInc.title = { [Op.like]: '%' + query.trim() + '%' };
}
if (req.body.date_from !== -1 && req.body.date_to !== -1) {
if (req.body.date_from != "") {
whereObjInc.createdAt = { [Op.gte]: req.body.date_from };
}
if (req.body.date_to != "") {
whereObjInc.createdAt = { [Op.lte]: req.body.date_from };
}
if (req.body.date_to != "" && req.body.date_from != "") {
whereObjInc.createdAt = { [Op.between]: [req.body.date_from, req.body.date_to] };
}
}
if (req.body.is_archive !== -1) {
whereObjInc.is_archive = req.body.is_archive;
}
let customOrder = [[order_by, order_by_ASC_DESC]];
if (order_by == 'title') {
customOrder = [[{ model: Ticket }, order_by, order_by_ASC_DESC]];
}
let orderByCondition = [[order_by, order_by_ASC_DESC]];
if (order_by == 'company') {
orderByCondition = [[{ model: Company, as: 'reported', }]];
//orderByCondition = [[{ model: Company, as: 'reported' }, 'company_name', order_by_ASC_DESC]];
}
if (order_by == 'accountable') {
orderByCondition = [[{ model: Company, as: 'accountable' }, 'company_name', order_by_ASC_DESC]];
}
if (order_by == 'reported_by') {
orderByCondition = [[{ model: Ticket},[{ model: User }, 'first_name', order_by_ASC_DESC]]];
}
let order_type = ['company', 'accountable', 'reported_by'];
if (order_type.includes(order_by)) {
[err, tickets] = await to(TicketAssignment.findAll({
where: whereObj,
include: [{ model: Ticket, where: whereObjInc }],
limit: limit,
offset: offset,
order: orderByCondition,
}));
}
