This is the Mongo db collection

"particulars":[
{
"serialNo": 1,
"item": "desk",
"link": "http//",
"images": "http//",
"quantity": 13,
"unitPrice": 100,
"amount": 1300
},
{
"serialNo": 2,
"item": "desk",
"link": "http//",
"images": "http//",
"quantity": 13,
"unitPrice": 100,
"amount": 1300
},
{
"serialNo": 3,
"item": "desk",
"link": "http//",
"images": "http//",
"quantity": 13,
"unitPrice": 100,
"amount": 1300
}
]

the array from frontend is this
procurement_details:[
{
"serialNo": 1,
"item": "ac",
"link": "http//",
"images": "http//",
"quantity": 1,
"unitPrice": 100,
"amount": 100

"serialNo": 2,
"item": "fan",
"link": "http//",
"images": "http//",
"quantity": 1,
"unitPrice": 100,

var bulk=await tickets.initializeOrderedBulkOp()
for(procurement_detail of procurement_details){
const resultt=await tickets.find({"_id":mongodb.ObjectId(ticketId),"particulars.serialNo":procurement_detail.serialNo},{projection:{"particulars.$":1,_id:0}}).toArray()
console.log("resultts",resultt);
await bulk.find({"_id":mongodb.ObjectId(ticketId),"particulars.serialNo":procurement_detail.serialNo}).update({
$set:{"particulars.$":procurement_detail},
$push:{ticketHistory:{$each:resultt[0].particulars}}
})
}
await bulk.execute()
