Moto: creating mock dynamodb table fails with TypeError: list indices must be integers, not unicode

[dtenenba]

Python 2.7.10 (yes, the project needs to upgrade)
moto==1.1.25
boto3==1.4.8

The following code returns an error (pasted below).

from moto import mock_dynamodb
import boto3


@mock_dynamodb
def testit():
    dynamo = boto3.client('dynamodb', region_name='us-west-2')
    dynamo.create_table(TableName='economy-cloud-users',
                        AttributeDefinitions=[{'AttributeName': 'user_name',
                                               'AttributeType': 'S'}],
                        KeySchema=[{'KeyType': 'HASH', 'AttributeName': 'user_name'}],
                        ProvisionedThroughput={'ReadCapacityUnits': 5,
                                               'WriteCapacityUnits': 5})


if __name__ == '__main__':
    testit()

Output:

TypeError: list indices must be integers, not unicode

The same error does not happen in real AWS (if I comment out the decorator), it just creates the table.

You're using boto3. Use @mock_dynamodb2.

[dtenenba]

That did it, thanks.

I believe when to use @mock_dynamodb2 should be mentioned more clearly in the docs
