Can't update records which have datafeeds set (server error: invalid feed pointer)

[igor-raits]

import ns1
api = ns1.NS1(apiKey='[…]')
record = api.loadRecord('cloud.na3.pcigdc.com', 'A')
record.update(ttl=3)

results into

ns1.rest.errors.ResourceException: server error: invalid feed pointer

This is happening with 0.9.19 release.

I'm having trouble recreating this error in python3.7 using the requests transport. Can you enable verbose logging and print the output (example below)?

import logging
import ns1
logging.basicConfig(level=logging.DEBUG)
config = ns1.Config()
config.createFromAPIKey('[...]')
config['verbosity'] = 5
api = ns1.NS1(config=config)
rec = api.loadRecord('cloud.na3.pcigdc.com', 'A')
rec.update(ttl=3)

Also, can you confirm the configuration on the NS1 side? Is your top level zone pcigdc.com or na3.pcigdc.com?

During handling of the above exception, another exception occurred:

Yes, changing configuration using web interface works.

Trouble with recreating was on my end, sorry about that.

I can recreate the issue via curl, so it's looking like this is not a bug with the python module, but with the API itself. This issue occurs when a POST call is made whose body does not explicitly include the answer, meta and full value of the defined metadata type for any answer that has a datafeed set.

I've created a bug internally so NS1's backend team can take a look at this. Will follow up when I have more info on progress there.

As an update here, this has been accepted as a bug with the API by NS1's backend team and has been added to their backlog. I'll close this issue out once that has been completed.

In the mean time, the record can still be updated as long as the full answer that has the datafeed defined is included with the update. So the workaround here would be to include the answers returned by loadRecord as a parameter toupdate. I.e:

import logging
import ns1
logging.basicConfig(level=logging.DEBUG)
config = ns1.Config()
config.createFromAPIKey('[...]')
config['verbosity'] = 5
api = ns1.NS1(config=config)
rec = api.loadRecord('cloud.na3.pcigdc.com', 'A')
rec.update(ttl=3, answers=rec.data['answers'])
