Authentication token in React.js

I want to set the authenticate token as a key-value pair in a react-js like x-access-token(key) = JWToken.value

I am generating the token like following in the backend:

module.exports = middlewares = {
  authenticateToken: async (req, res, next) => {
    try {
      if (
        !req.headers["x-access-token"] ||
        req.headers["x-access-token"] === ""
      ) {
        return res.failed(401, "Key x-access-token not found");
      }

      const token = req.headers["x-access-token"];
      const data = jwt.verify(token, keys.JWToken);
      if (!data) return res.failed(401, "Invalid token");
      req.data = data;

      next();
    } catch (error) {
      return res.failed(500, "Internal server error", error);
    }
  },
};

How can I do that because whenever I send the request to the protected route I am getting the Unauthorized error which is obvious.

the data stored in the local storage:

{flag: true, code: 200, data: ..., message: "Logged in successfully", error: null}
code : 200
data : 
   JWToken : "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6IjYzMjQ9MzRjOTQxNTMxMTYzZDIwMDFhYSIsImlhdCO8MTY2xzgzMjcyNywiZXhwIjoxMjk1Mzg5NjUzfQ.JOO1Cy8-7M4_kFHxRyK6g48s9vR2xXSB3pOpAzw3UgS"
   user : {_id: "6324734c941531163d2001aa", email: "[email protected]", phone_number: "1334567891"}
     email : "[email protected]"
     is_verified : true
     role : "admin"
     _id : "6324734c941531163d2001aa"
     error : null
     flag : true
     message : "Logged in successfully"

The package action file:

export const createPackage = (packageData) => async (dispatch, getState) => {
  try {
    dispatch({ type: PACKAGE_CREATE_REQUEST });

    const {
      adminLogin: { adminInfo },
    } = getState();

    const config = {
      headers: {
        "Content-Type": "application/json",
        Authorization: `${adminInfo.data.JWToken}`,
      },
    };
    const { data } = await axios.post(
      "http://localhost:8000/v1/package/add_package",
      packageData,
      config
    );
    dispatch({ type: PACKAGE_CREATE_SUCCESS, payload: data });
  } catch (error) {
    dispatch({
      type: PACKAGE_CREATE_FAILURE,
      payload:
        error.response && error.response.data.message
          ? error.response.data.message
          : error.message,
    });
  }
};
