Answer 1

you are redirect to localhost, it's not url valid because is not public on internet

Answer 2

Please try below URLs

Cognito Setting: Cognito User Pool --> "Sign in and sign out URLs" → "Callback URL(s)" →

Value to be added : ",https://localhost/dashboard,https://localhost/oauth2/idpresponse,"

If this does not work then try adding port as well.
