cant log to the console terminal

I'm trying to log data to the console in my node project and nothing happened. i use a middleware function before GET and there is no log

exports.protect = catchAsync(async (req, res, next) => {
  //1)Getting token and check of its there
  let token;
  if (
    req.headers.authorization &&
    req.headers.authorization.startsWith('Bearer')
  ) {
    token = req.header.authorization.split(' ')[1];
  }
  console.warn(token);
  //2) verification token
  //3) check if user still exist
  //4) check if user change password afterr token made
  next();
});
