AWS Lambda ERROR: AttributeError 'list' object has no attribute 'get'

Question

I have a Lambda function that is designed to turn ON/OFF my Philip HUE lightbulbs. I am able to execute the python script & it runs (error-free) on my local machine. However

Answer 1

The issue with changing the value of internal_dict_value during the loop is you dont know what type it's going to hold. try something like if type(internal_dict_value) is dict:

Answer 2

With the help of @JakePearse I was able to resolve the issue.

Here is the final version of my (fully-functional) python script.

import requests,json

bridgeIP = "IP/FQDN_Here:port_here"
userID = "userHash_here"
lightID = "2"

def lambda_handler(event, lambda_context):
    url = f"http://{bridgeIP}/api/{userID}/lights/{lightID}"

    r = requests.get(url)
    data = json.loads(r.text)

    def nested_get(input_dict, nested_key):
        internal_dict_value = input_dict
        for k in nested_key:
            if type(internal_dict_value) is dict:
                internal_dict_value = internal_dict_value.get(k, None)
                if internal_dict_value is None:
                    return None
        return internal_dict_value

    bulbStatus = nested_get(data,["state","on"])

    if bulbStatus == False:
        requests.put(f"{url}/state",json.dumps({"on":True}))
    elif bulbStatus == True:
        requests.put(f"{url}/state",json.dumps({"on":False}))

    return {
        'statusCode': 200,
        'body': json.dumps('Mission accomplished!')
    }
