Subdomains Causing Issues with Sourcemaps

Wix

Hello, I have noticed an issue with Raygun and sourcemaps. Our SaaS system uses subdomains to identify customers. So, customerA.website.com. All our scrips are in /scripts but they resolve to customerA.website.com/scripts/. Raygun won't pick up the sourcemaps unless I specify the full url for each customer. Is there a work around for this? The only option I can think of other than posting sourcemaps for each subdomain is putting calling scripts at the base URI and dealing with CORS.

Hi,

You can utilize a single set of source maps by normalising the URL's reported in the stacktrace then uploading a set of file with normalised URLs.

You can ensure your stacktraces are normalized by utilizing a onBeforeSend handler in raygun4js.

//handler method
var beforeSend = function(payload) {
    var stacktrace = payload.Details.Error.StackTrace;

    var normalizeFilename = function(filename) {
        var indexOfJsRoot = filename.indexOf("scripts");
        return 'http://normalizedurl.com/' + filename.substring(indexOfJsRoot);
    }

    for(var i = 0 ; i < stacktrace.length; i++) {
        var stackline = stacktrace[i];
        stackline.FileName = normalizeFilename(stackline.FileName);
    }
    return payload;
}

//attaching the handler to the Raygun provider
rg4js('onBeforeSend', beforeSend);

Alternately you can make your scripts be publicly available or hosted from the same URL.

Let me know if you have any further questions.

Regards, Alex
