I am not sure but I see this message: Error: connect ECONNREFUSED 127.0.0.1:8080

So how is this related to this error: Error: connect ECONNREFUSED 127.0.0.1:8000?
This is something I experience when I try to send a POST request to the server through Postman.

Not sure how. But have you checked again you code or if there is something wrong in postman request. In my scenario that is how it got fix. I can not exactly explain…
