Hello

Some times, I get this error reported:

my_project.js:1 Uncaught TypeError: Cannot read properties of null (reading 'get_frameRate')
    at _0x13b57c.__updateMouseDrag (my_project.js:1:1181946)

I am out of ideas how to debug this or how to fix it, as its our of my application scope.
I am using:

I think that this change I committed a couple of weeks ago will fix your issue:

Thanks @joshtynjala, I will try that. I didn’t know that __updateMouseDrag is in TextField class

It seems that the develop branch is not compatible with swf library ? as I got this error:

/usr/local/lib/haxe/lib/swf/3,0,2/src/swf/exporters/animate/AnimateSpriteSymbol.hx:41: characters 13-26 : Class<openfl.display.MovieClip> has no field __constructor

I’ve never used the swf library, so I can’t help much there. Maybe you need to use the dev version of that too?

Hi @hopewise, 3.0.2 and OpenFL Development version does not compatible.

Please downgrade your OpenFL version to 9.1.0
