AttributeError: 'InternalAsyncMqttClient' object has no attribute '_endpoint_provider'. Did you mean: 'set_endpoint_provider'?

I'm trying to use shadow functionality for IoT core

import boto3
import json
import time
import paho.mqtt.client as mqtt
from AWSIoTPythonSDK.MQTTLib import AWSIoTMQTTClient, AWSIoTMQTTShadowClient

# Set up the AWS IoT MQTT client
client = AWSIoTMQTTClient("myClientId")
client.configureEndpoint("redacted", 8883)
client.configureCredentials("redacted", "redacted", "redacted")

# Set up the AWS IoT shadow client
shadow_client = AWSIoTMQTTShadowClient("testIoTPySDK")

# Connect to AWS IoT and the shadow service
shadow_client.connect()

Failure

python3 pubsub.py

Looking at the code provided, I think the issue is that you have not configured shadow_client and instead configured client, which is separate from shadow_client. As seen in this sample, you need to setup the shadow client in order for it to connect.

In your case, I think can you adjust your code to the following:

import boto3
import json
import time
import paho.mqtt.client as mqtt
from AWSIoTPythonSDK.MQTTLib import AWSIoTMQTTClient, AWSIoTMQTTShadowClient

# Set up the AWS IoT shadow client
shadow_client = AWSIoTMQTTShadowClient("testIoTPySDK")
shadow_client.configureEndpoint("redacted", 8883)
shadow_client.configureCredentials("redacted", "redacted", "redacted")

# Connect to AWS IoT and the shadow service
shadow_client.connect()

and then it should work as expected.
