Try below code:

var inputString = {"Request":"{\"header\":{\"action\":\"SubmitRecordAndCalculateFees\",\"username\":\"PUBLICUSER\",\"trxId\":\"2c348091-3f1c-4ccb-b854-92cd5d164565\",\"language\":\"EN\"},\"body\":{\"recordNumber\":\"PTL-HPCAN-2022-00157\"}}"}

console.log(JSON.parse(inputString.Request).body.recordNumber)

Answer 2

Your string seems to be an invalid string, please check the below code on how to extract the desired output!

 const str = "{\"header\":{\"action\":\"SubmitRecordAndCalculateFees\",\"username\":\"PUBLICUSER\",\"trxId\":\"2c348091-3f1c-4ccb-b854-92cd5d164565\",\"language\":\"EN\"},\"body\":{\"recordNumber\":\"PTL-HPCAN-2022-00157\"}}"; const obj = JSON.parse(str); console.log(obj.body.recordNumber);
