How to get user session in Cognito after sign up or login via Google?

I set up authorization and login in the Cognito via Google. Now I need to get to the user attributes, but I don't understand how can I do it? Existing apis like getSession don't work,and throwing an error.

I use React and library 'amazon-cognito-identity-js'.

I loggin via Google this way:

const path = `https://${myDomain}.auth.us-east-1.amazoncognito.com/login?response_type=code&client_id=${clientId}&redirect_uri=${redirect}`;
router.push(path);

My email appears in User Pool - that's OK.

After successful redirect I call this code, because I need a session to get the user attributes:

const getSession = (role: TRoles): Promise<IReturnObj> => {
  return new Promise((resolve, reject) => {
    const user = MyPool.getCurrentUser();

if (!user) {
  reject(new Error('Current user not found'));
}

user.getSession((err: Error, session: CognitoUserSession) => {
  if (err) {
    reject(err);
  } else {
    resolve({session, user});
  }
    });
  });
};

In result I get undefined user and reject error. What I doing wrong?
