[SOLVED] my app is taking localhost:3000 as the server. but i have localhost:4000 as the server


This Content is from Stack Overflow. Question asked by mvsr cm

My problem is that iam using axios to communicate with backend.axios had done perfect job till now. but when i wrote a code for register, my console says that
POST http://localhost:3000/api/v1/register 500 (Internal Server Error)

so till now it responded very good.but now it thrwing an error like this.

userAction.js :

export const register = (userData) => async (dispatch) => {
  try {
    dispatch({ type: REGISTER_USER_REQUEST });

    const config = { headers: { "Content-Type": "multipart/form-data" } };

    const { data } = await axios.post("/api/v1/register", userData, config);

    dispatch({ type: REGISTER_USER_SUCCESS, payload: data.user });
  } catch (error) {
      payload: error.response.data.message,

iam using localhost:4000 as server. but it showing me localhost:3000 which means my app url


Because you did not specify the host in your post url.Then it may be work.

/api/v1/register => http://localhost/api/v1/register

The if you have cors issue add this to the nodejs backend app.js file (as you using nodejs):

const cors = require('cors');
