Getting an undefined variable message when calling Lambda function from Connect

0

I'm calling the code block below from Connect. I receive an error variable is undefined. Within connect when I test using the JSON { "key1": "654321" } The code works properly

From Connect the calling block is set up Function = alias of the Lambda function Function input parameters: Use attribute Destination key: key1 type: system Attribute: Customer ID

To me, it appears that the Parameters being passed in the Connect JSON string are correct.

Any help as to why the data is not being parsed properly when sent through Connect would be greatly appreciated

Logs show valid data being passed to the function { "Results": "The Lambda Function Returned An Error.", "ContactId": "e56bdf6c-923d-49d8-", "ContactFlowId": "arn:aws:connect:us-west-2:507182563096:instance/0cb6a294-6586-4aa3-b7cc-2b0f1516e0df/contact-fl", "ContactFlowName": "Connect-VoiceID-CareGiver-Contact-Flow_15", "ContactFlowModuleType": "InvokeExternalResource", "Timestamp": "2022-04-03T21:19:58.785Z", "ExternalResults": { "value": "707777", "attribute": "cid" }, "Parameters": { "FunctionArn": "arn:aws:lambda:us-west-2:507182563096:function:RHCS-VID-SMS", "Parameters": { "key1": "707777" }, "TimeLimit": "3000" } } Connect log shows:

Lambda log shows : INFO UI = undefined

const AWS = require('aws-sdk'); exports.handler = async (event) => {

AWS.config.update({region: 'us-west-2'});
var params = {

};

// Create promise and SNS service object
var publishTextPromise = new AWS.SNS({apiVersion: '2010-03-31'}).publish(params).promise();

return new Promise((resolve, reject) => {
    // Handle promise's fulfilled/rejected states
    publishTextPromise.then((data) => {
        console.log("MessageID is " + data.MessageId);
        const response = {

            headers: {
                "Content-Type": "application/json"
            },
            body: JSON.stringify(data)
        };
        console.log('Server response function');
        resolve(response);
    }).catch((error) => { reject(Error(error)); });
});

You should provide Lambda's logs because the error is from Lambda.

When you're testing the Lambda are you using the right JSON string that mimics what Connects sends? I don't see where you get the right JSON parameter, I suspect that's the issue.

The Connect log seems to show that it is sending: "FunctionArn": "arn:aws:lambda:us-west-2:507182563096:function:RHCS-VID-SMS", "Parameters": { "key1": "707777" }, "TimeLimit": "3000" } } Key1 would be correct and the target variable UI is defined console.log("UI = " + event.key1).
