This article shows you the steps of storing your Backtrace project crash&error report to brainCloud custom entities with a Unity app that has Backtrace integrated.

Step1: Create a webhook with a linked script from brainCloud console

  • Login to brainCloud console, select an app for storing backtrace reports, create a custom collection, set the Owned property to true if you want to classify the reports by users.

  • Create a Webhook and link the following script to this Webhook. Note that to change the entityType name to your custom collection name and default user profileId accordingly. Check out this link for setting up webhook in brainCloud.

    "use strict";

    function main() {
    var response = {};
    bridge.logInfoJson("Script inputs", data);
    var webHookParms = JSON.parse(JSON.stringify(data));
    webHookParms.headers = safeMap(data.headers);
    webHookParms.parameters = safeMap(data.parameters);
    webHookParms.jsonBody = safeMap(data.jsonBody);
    webHookParms.jsonBody.attributes = safeMap(data.jsonBody.attributes);

    // for the case backtrace error coming but user not logging in yet
    // save the log to default user
    var profileId = "d5127546-b027-464d-bade-96b1832e97eb";
    if (data.jsonBody.attributes.profileId[0][0].length > 5 ){
    profileId = data.jsonBody.attributes.profileId[0][0];
    }

    bridge.logInfo("passed in profileId from backtrace", profileId);

    bridge.logInfoJson("Received the webhook start...", data);

    var userSession = bridge.getSessionForProfile(profileId);

    //store backtrace jsonBody to an owned custom entity
    var entityType = "backTraceReport";
    var dataJson = {
    "fingerprint": data.jsonBody.fingerprint,
    "jsonBody": webHookParms.jsonBody
    };
    var acl = {
    "other": 1
    };
    var timeToLive = null;
    var isOwned = true;
    var customEntityProxy = bridge.getCustomEntityServiceProxy(userSession);

    var postResult = customEntityProxy.createEntity(entityType, dataJson, acl, timeToLive, isOwned);
    if (postResult.status == 200) {
    response.createdEntityStatus = "successfully create a custom entity with fingerprint " + webHookParms.jsonBody.fingerprint;
    }

    var logService = bridge.getLogServiceProxy();
    logService.logInfo("Webhook [ " + webHookParms.requestUrl + " ] - dumping parameters...", JSON.stringify(webHookParms));

    response.jsonResponse = {};
    response.message = "Webhook received";
    response.jsonResponse.receivedInCCdata = data;

    return response;
    }

    function safeMap(aMap) {
    var newMap = {};
    var newKey = "";
    for (var key in aMap) {
    newKey = key.replace(/\./g, "_");
    newMap[newKey] = aMap[key];
    }
    return newMap;
    }

    main();

Step2: Set up a project in Backtrace

  • Login to your backtrace account, create a project then go to Project settings. Following their integration guides to integrate backtrace to your platform accordingly, our example uses Unity.

  • Go to Workflow integrations section, add brainCloud webhook to there.

  • Open Attribute section, add a profileId attribute to there, we will use it in the Unity app.

  • If your app uses backtrace API, generate one from the API tokens section.

Step3: Send out Backtrace report from the Unity app

  • Once you follow backtrace integration guides to integrate backtrace to your Unity app, make sure to add backtrace send report method to each brainCloud error call back.

    public void authError_BCcall(int statusCode, int reasonCode, string statusMessage, object cbObject)
    {
    AddStatusText("authenticate bc fail \n " + statusMessage);

    var report = new BacktraceReport(
    message: statusMessage,
    attributes: new Dictionary<string, string>() { { "attibutestest", "attibutestestvalue" }, { "profileId", profileId } },
    attachmentPaths: new List<string>() { @"file_path_1", @"file_path_2" }
    );
    _backtraceClient.Send(report);
    //_backtraceClient.Send(new Exception(statusMessage));
    }

Step4: Check the error from backtrace dashboard and brainCloud console

  • Run your Unity app generate some error, check it from backtrace dashboard.

  • Check if the brainCloud webhook script gets called from brainCloud console Monitoring page.
