[koorukuroo]

There are TypeError for register like #69

I try to it in branch of master, develop, features... But these have same error.

u.add_base_attributes(email='test@gmail.com')
u.add_custom_attributes(state='virginia', city='Centreville')
u.register(username='xxx', password='qwerty234@$')

I am experiencing the same issue.

Found the error @koorukuroo

u = Cognito('eu-west-1_xxxx', 'xxxx', client_secret='xxxxx',username='test@test.com')

u.add_base_attributes(email='test@test.com',locale='nl_NL',given_name='Test',family_name='Test')

u.register('test@test.com','Test1234!')

You have to add the username to Cognito() as well.

I'm experiencing the same issue as well. @BabyDino or @koorukuroo - were either of you able to figure out the issue/solution for this?

[BabyDino]

See my code above, did you add username='test@test.com'?

[dperconti]

I ended up creating a client without a secret (still without username), which is now working. Thanks!
