Question

I’m working on boto versioned 2.6.0 . I have a problem with connecting to mturk.
My code is :

mturk_connection = MTurkConnection(aws_access_key_id=ACCESS_ID, aws_secret_access_key=SECRET_KEY, is_secure = True, host = HOST)
print mturk_connection.get_account_balance()

The error message i get is :

boto.mturk.connection.MTurkRequestError: MTurkRequestError: 200 OK  
<?xml version="1.0"?>
    <GetAccountBalanceResponse>

I tried finding out the source of the error but failed. Please suggest something.

I guess you have the older version of boto where bug fix #1057 hasn’t been updated.please check line number 525 for an ‘init’ method.If you don’t find one .. re-clone the boto repository from github again and install using the command –

python setup.py install

Hope your problem gets solved.
