app.js:166 Uncaught ReferenceError

[vk-gst]

I am trying to use this code to host on ec2 on AWS. I have followed the same steps as mentioned in the blog. However I face the following issue:

recordButton clicked                                                                 app.js:45
getUserMedia() success, stream created, initializing Recorder.js ...                 app.js:73 
Recording started                                                                    app.js:98 
stopButton clicked                                                                   app.js:166
 Uncaught ReferenceError: recordingsList is not defined
    at createDownloadLink                                                            (app.js:166)
    at Worker.Recorder.worker.onmessage                                              (recorder.js:238)

I have no clue why this is occuring. The microphone access is enabled. But however nothing is being recorded.

Could you please let me know where, I am going wrong with this one?
