Document Schema

const transaction = new mongoose.Schema({
    id: {type: Number, required:true},
    greeterAddress: {type:String, required:true},
    executed: {type:Number, required:true},
    value: {type:String, required:true},
    approved:{type: [String]}
})
const walletInfo = new mongoose.Schema({
    walletAddress: {type: String, required: true},
    networkName: {type: String, required:true},
    minApproval: {type: Number, required:true},
    ownerAddress: {type: [String]},
    greeter: {type: [String]}, 
    transactionList: {type:[transaction]}
})

Executed code which is giving out the error

app.post('/approve_transaction', async(req,res)=>{
    walletAddress = req.query.address
    id =  req.query.id
    greeterAddress =  req.query.greeterAddress
    await walletInfo.updateOne(
        {
            walletAddress:walletAddress,
            'transactionList.id':id,
            'transactionList.greeterAddress':greeterAddress
        },
        {
            $push:{
                'transactionList.approved':walletAddress
            }
        })
    res.sendFile('success')
