[Help] First argument contains NaN

I'm working on my first script using the API and in testing it will eventually crash with this stack trace: /home/symbly/www/d20-api-server/node_modules/firebase/lib/firebase-node.js:1 orts, require, module, __filename, __dirname) { function g(a){throw a;}var j=v ^ Error: Firebase.update failed: First argument contains NaN in property 'rotation' at Error ( ) at Ba (/home/symbly/www/d20-api-server/node_modules/firebase/lib/firebase-node.js:9:186) at Ba (/home/symbly/www/d20-api-server/node_modules/firebase/lib/firebase-node.js:10:207) at Aa (/home/symbly/www/d20-api-server/node_modules/firebase/lib/firebase-node.js:8:462) at Ea (/home/symbly/www/d20-api-server/node_modules/firebase/lib/firebase-node.js:10:403) at H.J.update (/home/symbly/www/d20-api-server/node_modules/firebase/lib/firebase-node.js:146:318) at TrackedObj._doSave ( The top of the stack is outside my code so I'm having a tough time tracking down how to fix it. I added a try / catch where I access the rotation property of the object, but it looks like execution isn't getting to there. Any help on fixing issues like this? By the way my script is an event handler on "change:graphic" and it works well for a while until eventually this happens.

Just figured out my script was setting rotation to NaN under some scenario. Now I just need to figure out why :)

Nobody can help you if we can't see your code. =)

Haha good point :) Never actually tracked down what the root cause was, but in the course of cleaning up the script the issue went away. Here's the script if you want to take a look at what I ended up with:&nbsp;<a href="https://app.roll20.net/forum/post/2617353/help-rotate-token-on-move" rel="nofollow">https://app.roll20.net/forum/post/2617353/help-rotate-token-on-move</a> . If you have any tips or optimizations to what I'm doing I'm very interested.
