i am getting data on my local port : 9999 node app but facing 502 error while running the same app on the netlify

I got this error while making a get request to a node app deployed on netlify. I was able to get data of the same app when I am running it on my local port 9999, basically the connection is correct to mongoDB.

I tried running my app on my local port 9999 and I received all data in GET request, but it is not happening when I run the same app on netlify deployed app. Kindly assist.

Solution

"useNewParser : true" in mongoose.connect(URI , {useNewParser:true}) worked in my case , as i just followed every option given in mongoose document of mongoose connection .
