KeyError: 'cidr_prefix_length' when listing IP access control lists

[ruipserra]

I'm trying to use the REST API to check that certain IP addresses are part of some predefined IP ACLs, and create them if necessary.

I'm getting a KeyError: 'cidr_prefix_length' while trying to list the IP addresses in the IP ACL.

Package Version: 6.16.3
Python Version: Python 2.7.15

Code Snippet

from twilio.rest import Client

account_sid = "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
auth_token = "my_auth_token"
client = Client(account_sid, auth_token)

ip_access_control_lists = client.sip \
    .ip_access_control_lists \
    .list()

ip_access_control_lists[0] \
    .ip_addresses \
    .list()

    'cidr_prefix_length': deserialize.integer(payload['cidr_prefix_length']),
KeyError: 'cidr_prefix_length'    

I tried logging the content of payload (some values removed):

{
  u'date_updated': u'Wed, 29 Aug 2018 20:12:21 +0000', 
  u'friendly_name': u'Mike in the office', 
  u'uri': u'/2010-04-01/Accounts/ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/SIP/IpAccessControlLists/ALXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/IpAddresses/IPXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.json',
  u'ip_access_control_list_sid': u'ALXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX', 
  u'account_sid': u'ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX', 
  u'sid': u'IPXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX', 
  u'date_created': u'Wed, 29 Aug 2018 20:12:21 +0000', 
  u'ip_address': u'XXX.XXX.XXX.XXX'
}

Let me know if you need any other information.

Thanks in advance! 🙌

👍

This is not a change that can be made in the library. An internal ticket has been filed against the relevant product team.

[childish-sambino]

After speaking with the product team, I believe this occurs when new properties are added but not available to all customers during preview, beta, rollout, etc.

Since the other helper libs do not throw errors when properties are missing, neither should this one.

Adding this to the backlog to be prioritized. Pull requests and +1s on the issue summary will help it move up the backlog.
