KeyError 'EventSourceArn' when running status

[steinnes]

Hi, I am very new to Kappa, and was using it to check the status of an existing lambda task we are using, and I get a key error for 'EventSourceArn':

  File "/Users/ses/w/lemonade-tasks/venv/bin/kappa", line 125, in status
    event_source['EventSourceArn'], event_source['State'])
KeyError: 'EventSourceArn'

(I suppressed the rest of the stack trace, it was just a few frames of click internals).

Here is the event_source dict (the only event source I have for this lambda function in fact):

{u'Endpoint': 'arn:aws:lambda:eu-west-1:575.....:function:sendEmailVerificationEmail',
 u'Owner': '575.....',
 u'Protocol': 'lambda',
 u'SubscriptionArn': 'arn:aws:sns:eu-west-1:575.....:accounts-email_verify_started:89abcdef-1234-1234-1234-456789abcdef',
 u'TopicArn': 'arn:aws:sns:eu-west-1:575.....:accounts-email_verify_started'}

I suppressed our actual IDs and stuff.

I wouldn't mind fixing this issue myself, but as I am so new to lambda I'm not sure why it is happening or which of these fields should replace the EventSourceArn in this case, or if this is a case of me having an incorrect boto version or something (boto3==1.1.0, kappa==0.3.1 FYI).

I just checked the kappa requirements and noticed boto3==0.0.22 there, so I cleaned my venv and installed that version:

$ pip freeze
boto3==0.0.22
botocore==1.0.0rc1
click==4.0
docutils==0.12
futures==2.2.0
jmespath==0.7.1
kappa==0.3.1
python-dateutil==2.4.2
PyYAML==3.11
six==1.9.0
wheel==0.24.0

Still getting the same error as before though.
