Python KeyError

0

Hello AWS Team, Can some one please help me here, I am trying to deploy the solution as advised in the blog https://aws.amazon.com/blogs/contact-center/recovering-abandoned-calls-with-amazon-connect/ , however when I run a test on Python 3.7 Lambda code as given, I am getting below error:

Response { "errorMessage": "'Records'", "errorType": "KeyError", "stackTrace": [ " File "/var/task/ACR.py", line 18, in lambda_handler\n for record in event['Records']:\n" ] }

Can some one please assist me with correct "Test Event" i should configure and also how can i get this error resolved? Thanks, Anchal

Hi there,

I have checked the code in the example and event you are looking for is "Kinesis record event", here is an example from documentation:

https://docs.aws.amazon.com/lambda/latest/dg/with-kinesis.html

You can create an example event for to test your Lambda function locally.

Kind regards,

Alex

Hello Thanks for sharing the test event, however please if you can run the code and test it, its giving that KeyError can you please check and validate code provided is correct? As its not recognizing 'Records' in the library for Python?

Hi Again,

As you can see after the Kinesis Record, test event i run, the below error i get : { "fail_code": "decode data fail", "result": "fail", "ctrs_processed": 0, "ctrs_skipped": 0 }

Seems its giving payload error in the Lambda function provided?

Decode the data and parse the json

    try:
        payload = base64.b64decode(record['kinesis']['data'])
        payload_data = json.loads(payload)
    
    # Log a decode failure and break out of loop
    except:
        response.update({'fail_code':'decode data fail'})
        response.update({'result':'fail'})

Please if you can help, will be apreciated.

Thanks, Anchal
