Cannot export or print schedule [AngularJS]

Asked by Pierre Veber

From my controller I'm trying to call exportAs().print() but I get an exception:
String expected
print @ schedule.controller.js?0afb:116
fn @ VM14359:4
callback @ angular.js?10a4:27341
$eval @ angular.js?10a4:18423
$apply @ angular.js?10a4:18523
(anonymous) @ angular.js?10a4:27346
dispatch @ jquery.js?eedf:5226
elemData.handle @ jquery.js?eedf:4878

The code is really simple:
print($event) {
$event.preventDefault()
let options = {
area: 'viewport'
}
try {
this.scheduler.exportAs('svg', options).download()
}
catch (e) {
console.error(e)
}
}

There is a similar issue reported one month ago in the forum but without response.

Please advice for hints and workarounds. Printing/exporting is a critical feature in my application.
Could it be an issue with jquery / AngularJS?

It looks like one of the values in the exported Scheduler is a number instead of a text. This is a bug - it should accept other reasonable values as well (including numbers).

It might be an event text (events[x].text) or a custom html value assigned in one of the rendering event handlers (e.g. onBeforeEventRender).

Could you please give it a try and let me know if this is the case?

Update: The latest sandbox build (8.4.3098) accepts string, number and null (null was added in this build). The exception text now includes the value type.

Please let me know if the problem persists.
