Telemetry upload bug if telemetry list is not ordered by timestamp or if elements of list have different number of key/value pairs

I'm using tb-mqtt-client version 1.10.10

I have a use-case where I'm uploading a list of telemetry readings. Depending on the order of the list, sometimes not all telemetry is being uploaded and sometimes the timestamp with which it is being uploaded is incorrect...

I first though that the list needed to be sorted by the timestamp attribute but then I had cases where even if it was sorted by timestamp it would work fine. It seems to be a combination of the list not being sorted with each element of the list not having the same number of key/value pairs.

I can't figure out or understand this behavior so any help would be appreciated.

This is the code snippet I'm using for testing this problem:

from tb_device_mqtt import TBPublishInfo
from tb_gateway_mqtt import TBGatewayMqttClient

telemetry =[...]

client = TBGatewayMqttClient("my.url.com", port=1883, username="token")
client.connect()

result = client.gw_send_telemetry('test device', telemetry) 

success = result.get() == TBPublishInfo.TB_ERR_SUCCESS
client.disconnect()

print(success)

Following are some examples of the problem where the only thing I'm changing is the order of the telemetry list:

Example 1 - works fine

telemetry =[
    {
        'ts': 1736330010000,
        'values': {
            'test_1': 1,
            'test_1_1': 1,
        }
    },
    {
        'ts': 1736330030000,
        'values': {
            'test_3': 3,
            'test_3_1': 3,
        }
    },
    {
        'ts': 1736330020000,
        'values': {
            'test_2': 2,
            'test_2_1': 2
        }
    },
]

Example 2 - does not upload test_2 and test_2_1 telemetry

telemetry =[
    {
        'ts': 1736330010000,
        'values': {
            'test_1': 1,
            'test_1_1': 1
        }
    },
    {
        'ts': 1736330020000,
        'values': {
            'test_2': 2,
            'test_2_1': 2
        }
    },
    {
        'ts': 1736330030000,
        'values': {
            'test_3': 3
        }
    },
]

Example 3 - test_1 and test_1_1 are being uploaded with the wrong timestamp. They are being uploaded with the same timestamp as test_3

telemetry =[
    {
        'ts': 1736330010000,
        'values': {
            'test_1': 1,
            'test_1_1': 1,
        }
    },
    {
        'ts': 1736330030000,
        'values': {
            'test_3': 3,
        }
    },
    {
        'ts': 1736330020000,
        'values': {
            'test_2': 2,
            'test_2_1': 2
        }
    },
]

まず、TBGatewayMqttClient.gw_send_telemetry を通じて 3 つのテレメトリ例を再現し、アップロードされた結果を比較します。テレメトリのアップロードパスを追跡して、リストの順序と値の長さの違いがタイムスタンプとエントリにどのような影響を与えるかを特定します。入力の順序や形状にかかわらず、すべての値が対応するタイムスタンプとともにアップロードされれば完了です。
