Unable to locate the LMS's API Implementation

Hi, I created my learning materials using Articulate Rise but I was unable to locate the LMS's API using a wrapper.js build on top of the indexAPI.html. The project is exported with setting of SCORM 2004 4th edition.

var theAPI = findAPI(window);
if ((theAPI == null) && (window.opener != null) && (typeof (window.opener) != "undefined")) {
theAPI = findAPI(window.opener);
}
if (theAPI == null) {
message("Unable to find an API adapter");
}

I want to get what my users has selected in the quiz section and then port the result to an external API created by my team.

Please advise. Thank you!
