an upstream system is making a get req to out system with utf-8 encoded even the ? is encoded.

the sample url is --> http://localhost:3000/hello%3FfirstName%3DPaperTest%26lastName%3DAddressMerge%26typeOfIdProof%3DEmirates+ID%26idProofNumber%3D123--2%26nationality%3DARE%26sourceSystem%3DDealer+App%26dateOfBirth%3D2001-09-29%26userId%3D111%26transactionId%3D9162655831313265133%26segmentName%3DN%2FA%26productType%3DTshirt

my express app could not get the query string from the above so i created a middle ware

    const app = express()
    const qrystr = require("querystring")
    
    app.set("query string","extended")
    app.use((req,res,next)=>{
        let val = req.query.
        console.log(req.query)
        let qry = qrystr.parse(val)
        req.query = qry
        next()
    })
   app.get("/hello*",(req,res)=>{
    let val = {...req['query']}
   // console.log(val)
    console.log(req.params)
    res.send("OK")
})

but in req.query i am getting { '0': '?firstName=PaperTest&lastName=AddressMerge&typeOfIdProof=Emirates+ID&idProofNumber=123-123-1111-2&nationality=ARE&sourceSystem=Dealer+App&dateOfBirth=2001-09-29&userId=111&transactionId=9162655831313265133&segmentName=N/A&productType=tshirt' }

could any one could suggest how to parse the above url / req properly so i could get the value like we used to get in req.query
