To localize the error issue returned on the frontend when calling a method, you can follow these steps:
-
Check the browser console and network requests (Network) — ensure what response is coming from the server, status code, response body, and headers.
-
Client-side logging — add additional logs before calling the method and after receiving the response to understand where exactly the error occurs.
-
Check server logs — find the corresponding request and see if an error occurred on the server.
-
Repeat the request using tools like Postman or curl — verify if the error reproduces outside the frontend.
-
Check request parameters and data sent — the error might be related to incorrect input data.
-
Use a debugger — if possible, set breakpoints on the server or in the client code.
-
Check API versions and compatibility — the frontend and backend might be using different method versions.
This systematic approach will help narrow down the search area and identify the cause of the error.
