Adobe Animate 2019 File generating TypeError: Error #1009 #13

LazyCube on Newgrounds reported this:

So, I was making a flash animation with Adobe Animate CC 2019(The animation's render setting is ActionScript 3.0 and FlashPlayer 30). When the animation is finished, I rendered the animation with swivel. But then the program's crashed and these error codes appear: TypeError: Error #1009: Cannot access a property or method of a null object reference. Method(haxe.io.BytesInput,readBytes) Method(haxe.io.Input,readAll) Method(format.swf.Reader,readHeader) Method(format.swf.Reader,read) Method(com.newgrounds.swivel.swf.SwfUtils,getSwf) Method(com.newgrounds.swivel.swf.SwfUtils,_getAs3Tag) Method(com.newgrounds.swivel.swf.SwivelMutator,mutate) Method(com.newgrounds.swivel.SwivelController,runTask) Method(com.newgrounds.swivel.SwivelController,runTaskDelay)

I tried so many things to solve this problem but all the things didn't solve this. I changed the FlashPlayer settings for many times, added some scripts that might help with it, redownloaded the program several times, etcs.

This seems to either be an issue with the AS2 tag parser in swfutils that uses the as1 parser or the haxe format package itself.

For reproducability, https://www.homestuck.com/flash/hs2/00980/00980.swf is a fairly simple file that consistently triggers this error case.

This can be fixed in most cases by simply wrapping CID references in PlaceObject tags and ignoring errors, as per https://github.com/GiovanH/Swivel/blob/endOnRepeat/src/com/newgrounds/swivel/swf/ScaleFilterMutator.hx#L83 .

There are still some cases where this crashes the program, though.
