Receiving (Ruffle) Error dispatching event errors - similar experiences/ ideas how to debug/ resolve?

[uover822]

Describe the bug

Hi All :-) I'm configuring/ launching Ruffle as follows:

var ruffle = window.RufflePlayer.newest(),player = Object.assign(document.getElementById(obj.id).appendChild(ruffle.createPlayer()), {width: widthStr, height: heightStr, style: 'width: ' + widthStr + 'px; height: ' + heightStr + 'px', });
player.config = {autoplay:'auto', logLevel: 'info'};
player.load({ url: swfUrlStr });

With the following object:

<object type="application/x-shockwave-flash" id="container_app" name="container_app" align="middle" data="UI.swf" width="100%" height="100%" style="visibility: visible;"><param name="quality" value="high"><param name="bgcolor" value="#ffffff"><param name="allowscriptaccess" value="sameDomain"><param name="allowfullscreen" value="true"><param name="menu" value="false"><param name="flashvars" value="locale=en_US&amp;localeChain=en_US&amp;resourceModuleURLs=locales/UI-en_US.swf&amp;csp="><param name="scale" value="noscale"><param name="wmode" value="opaque"></object>

Has anyone experienced similar issues or have ideas how t debug/ resolve these?

Thanks

Expected behavior

Expecting UI to be presented. Currently receiving the following errors during loading:

ruffle_web-wasm_extensions.js:932 ERROR core/src/avm2/events.rs:428 Error dispatching event EventObject(EventObject { type: "complete", class: flash.events::Event, ptr: 0xa705e68 }) to handler FunctionObject(FunctionObject { ptr: 0x1456318, name: Ok("mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/internal::preloader_completeHandler()") }) : ReferenceError: Error #1065: Variable UserSettingsCategoriesLoadRequestEvent is not defined.

Unfortunately, this doesn't appear to be something you can do anything about directly.

The error is right - from looking at the UI.swf you provided, I don't see a class called UserSettingsCategoriesLoadRequestEvent defined anywhere. So it's either some missing side SWFs, or they exist but weren't loaded for some reason, or it's us missing some unknown to us way of defining event classes. I have no intuition of which of these it could be.

(btw, I also tried running your swf in the web demo and it didn't do anything, but it also didn't show your errors)

Thanks, @adrian17 :-) Hi All: I also just tried running my swf in the web demo - receiving the attached.

Perhaps this error 2032 is indicating an expected/ missing source stream?

[uover822]

Hi @adrian17 :-) What tool did you use to review the swf src/ code, btw?

[danielhjacobs]

Probably https://github.com/jindrapetrik/jpexs-decompiler. The devs for Ruffle use that often.
