aws cognito user pool domain - Invalid_Request

Question

I have created a user pool and setup domain with app client settings () to host sign up and sign in pages in the cognito itself. When I tried using the url similar to -

https://myDomain.auth.us-east-1.amazoncognito.com/login?response_type=code&client_id=fkjfkasjfkasjfdweinfskfsfsfnk&redirect_uri=https://google.com

in the browser I am redirected to

https://myDomain.auth.us-east-1.amazoncognito.com/error?error=invalid_request#

Note: I tried using Cognito User Pool and Facebook identity providers without OAuth2 enabled.

Am I missing something?
