callback is not a function

[shell1986]

Hello everyone.
Thanks for such a useful development.

After installing the latest version and initializing the script, an error appears in the console that it does not exist is not a function.
In my case, it is callback(null, instance), which reports that the application is ready, but judging by the code, this function is responsible for reporting errors.
It would be great if you fixed this error.

Thank you :-) To help figure out what's going wrong, can you share the code you've written?

Yes

fetch('/ajax.php?getPeaks='+sid)
    .then(response => {
        return response.json();
    })
    .then(fdata => {
        if (fdata.success) {
        (function(Peaks) {
         pks = Peaks.init({
            container: document.getElementById('waveform-container'),
            mediaElement: document.getElementById('video'),
            playheadColor: '#fff',
            playheadWidth: 3,
            showAxisLabels:false,
            showPlayheadTime: false,
            axisTopMarkerHeight: 1,
            axisBottomMarkerHeight: 1,
            zoomLevels: [ 2048, 4096],
            dataUri: {
                arraybuffer: fdata.success
            },
        });
         pks.on('peaks.ready', function() {
          outputer(assArr[evid]);
});

    })(peaks);
        }
    })

I first load the generated peak file and then initialize the script.

There needs to be a check that the callback is valid. But in the documentation we say peaks.ready is deprecated, so I would recommend that you provide a callback to Peaks.init(). The peaks.ready event won't fire if there are any initialisation errors.

Thank you very much for the explanation.
