contactAttributes

[nbaillie]

I found that ContactAttributes were not being passed via the Lambda behind the API to Connect.

From the Readme...

connect.ChatInterface.initiateChat({
  name: customerName,
  username: username,
  region: ${region},
  apiGatewayEndpoint: "https://${apiId}.execute-api.${region}.amazonaws.com/Prod",
  contactAttributes: JSON.stringify({
    "customerName": customerName
  }),
  contactFlowId: "${contactFlowId}",
  instanceId: "${instanceId}"
},successHandler, failureHandler)

I made the change bellow in the startChatContactAPI-StartChatLambda Lambda and it works now as i would have expected.
"Attributes": body["Attributes"],

return new Promise(function (resolve, reject) {
        var startChat = {
            "InstanceId": instanceId == "" ? process.env.INSTANCE_ID : instanceId,
            "ContactFlowId": contactFlowId == "" ? process.env.CONTACT_FLOW_ID : contactFlowId,
            // "Attributes": {
            //     "customerName": body["ParticipantDetails"]["DisplayName"]
            // },
            "Attributes": body["Attributes"],
            "ParticipantDetails": {
                "DisplayName": body["ParticipantDetails"]["DisplayName"]
            }
        };

and now works with

connect.ChatInterface.initiateChat({
                    name: customerName,
                    region: "eu-west-2", // TODO: Fill in
                    apiGatewayEndpoint: apiGatewayEndpoint,
                    contactAttributes: JSON.stringify({
                        "customerName": customerName,
                        "language_code": language_code
                    }),
                    contactFlowId: contactFlowId,
                    instanceId: instanceId
                }, successHandler, failureHandler);

Hope this might help others, i am using this to pass a language option in my case.
Could be this can be changed or perhaps it has a reason for being like this.
