I have made cluster of 3 blockstack-core and running atlas
i have followed this steps as while pushing zonefile
>>> import blockstack
>>> import base64
>>> data = "..." # this is the chunk data you will announce
>>> data_b64 = base64.b64encode(data)
>>> result = blockstack.lib.client.put_zonefiles('https://node.blockstack.org:6263', [data_b64])
>>> assert result['saved'][0] == 1
but in last assertion saved
is 0
what can be the possible solution ?
