RPC request data truncating list items

[Bob Hayes]

I have a customer attempting to get EX4300 snapshot data with the following script. The return output seen, when asking for json formatted output, is each FPC returns only one of the two partitions in the list. If they modify the request to text format they see both primary and backup partitions for each FPC. 

When I manually execute the rpc commands directly into the switch via a netconf session from cli, I get both partitions in json format.  

#### Manual netconf session command used

####  <rpc>

####      <get-snapshot-information format="json">

####              <media>internal</media>

####      </get-snapshot-information>

####  </rpc>

In this link https://codebeautify.org/jsonminifier/y2376e55d  I have saved the manual json output where both partitions show up. However, note the minified version shows only one partition! I don't know why that would happen unless this minifier is stumbling on the json output / list items? 

What is the proper way to report this sort of issue?

Thanks,

-Bob

## Customer script

import sys

from getpass import getpass

from jnpr.junos import Device

from jnpr.junos.exception import ConnectError

from jnpr.junos.utils.sw import SW

from lxml import etree

import json

junos_password = getpass("Junos OS or SSH key password: ")

with Device(host='x.x.x.x', user='username', passwd=junos_password, normalize=True) as dev:

    sw1 = dev.rpc.get_snapshot_information({'format':'json'},media='internal')

    print(sw1)

dev.close()

### Example customer output - cleaned up a bit to be readable. This output should have both primary and backup for fpc0 and fpc1
