Catch block running before Try block in signup process

Question

I'm experiencing an issue where the catch block in my signup process is running before the try block. When I attempt to sign up, the catch block displays the error message before the success message is shown. This behavior is unexpected, as I would expect the try block to execute first.

Here is the relevant code snippet:

const onSignup = async (values: any) => {
        try {
          setLoading(true);
          const response = await axios.post(`/api/users/signup`, values);
          const responseData = response.data;
          if (!responseData.error) {
            toast.success("Signup success", successState);
            router.push("/login");
          } else {
            if (responseData.error === "User already exists") {
              toast.error("User already exists", errorState);
            }
          }
        } catch (error: any) {
          toast.error(
            "An error occurred during sign in. Please try again later.",
            errorState
          );
        } finally {
          setLoading(false);
        }
      };

catch never runs before try. Possibly explanations for what you see include that onSignup is called multiple times or that your toaster displays messages in the wrong order. So do some debugging what the values passed to each call are, and what error is thrown. — Bergi

In dev mode, this may be happening due to multiple renders - Check out this thread - Why my nextjs component is rendering twice?

So, actually, your catch block is not called twice. The error you see is from the previous render.
