Why do WebStorm and VScode send requests differently?

Question

Express.js

Hello.
I had a problem when starting the project and trying to log in.
When launching a project in webstorm, a request is sent during authorization and in the response headers content type = application/json.
While if you run the project in vscode. The request is sent with content type = text/html
I don't understand why this happens and how to fix it?

No code no answer. Fortune-telling on the coffee grounds, I can answer that you did not explicitly set the content type in your code, so the IDE is trying to guess.
