When I am not passing token or passing invalid token while accessing protected url, it is giving me 401 error with "Unauthorised" message as plain text. I want that it should show error message as json.

app.use(async (ctx, next) => {
  try {
    await next();
  } catch (err) {
    logerr(err);
    ctx.status = err.status || err.code;
    ctx.body = {
      status: false,
      message: err.message,
    };
  }
});

It is not getting catched in the above function, but it is getting captured in below function.

app.on('error', (err, ctx) => {
  logerr('onerr ', err);
  if (err.name === "UnauthorizedError") {
      ctx.status = 401;
      ctx.body = "invalid token...";
   }
});

But it is not showing me "Invalid token" message but it is throwing "Unauthorised" error as plain text.
