Invoke Error

[23ewrdtf]

Hi,

When I run the npm run deploy I got below error:

message: The runtime parameter of nodejs8.10 is no longer supported for creating or updating AWS Lambda functions. We recommend you use the new runtime (nodejs12.x) while creating or updating functions.

So I run npm install node-lambda@latest and deploy was successful.

Now when I send a test message to subscription I get below error in Lambda:

2020-04-01T10:46:49.840Z    xxxxxxxxxxxxxxxxxxxxx   INFO    sns received:

        }
    ]
}

I just ran into the same error while testing the function. The stack trace tells you, that the error occurs in index.js:319 (see https://github.com/assertible/lambda-cloudwatch-slack/blob/master/index.js#L319)

The code tried to parse the message as json but what you are sending is text. Try sending a test message in valid json instead.
