Ok so I have got this weird error. I am passing user credentials via postman. In one tab, I am getting an error, but when another tab is used it works. As far as I have checked everything is same in both tabs of postman.

This shows the working tab in postman This shows the failed tab in postman

My first thought would be that the orange dots in the tabs at the top are indicating that you haven't saved your changes.

CodePudding user response：

One of your requests goes to localhost:5000 and one goes to localhost:3000, is that intentional? You are sending the same data to two different services, so it's possible that the response is different.
