JS Error for the Dictation content type

[emostoyanov]

Hi, I've installed recently your RTL version of H5P module in our Moodle environment and I am facing an issue with the latest Moodle version (3.9) and the Dictation H5P content type specifically. The H5P content iframe is not loaded and there is a JS error in the browser console:

Uncaught TypeError: Cannot read property 'getUsersScore' of undefined
at t. (h5p-x-api.js?ver=2020020500:125)
at t.call (h5p-event-dispatcher.js?ver=2020020500:209)

at Function.each (jquery.js?ver=2020020500:2)

This H5P content item was downloaded from their examples site. The rest of the h5p CTs are loaded all right. Tried in different Moodle themes, same result. If I use latest upstream version of H5P (1.21) the problem disappears and Dictation H5P iframe is displayed. I would be grateful if you can confirm the issue and eventually suggest a fix.

Thank you!

For the time being I was able to bypass the error by commenting few lines in library/js/h5p-x-api.js , the last function

H5P.externalDispatcher.on('xAPI', function (event) {
// if (event.getVerb() === 'answered' &&
if (event.getVerb() === 'answered') {
// And in case we have some interactive content inside "slides"...
// typeof this.parent.getUsersScore !== "undefined") {
// var total_score = this.parent.getUsersScore();
// var total_maxScore = this.parent.getUsersMaxScore();
var contentId = event.getVerifiedStatementValue(
['object', 'definition', 'extensions', 'http://h5p.org/x-api/h5p-local-content-id']);
if (H5P.opened[contentId] === undefined) {
H5P.opened[contentId] = new Date();
}
// H5P.setFinished(contentId, total_score, total_maxScore);

}
});

but in this way I think score reporting functionality is lost.
