API Crash- looking for error

I have a game tonight and logged in to the game and the API crashes immediately.  Worked fine a few days ago.  How would I go about determining what the issue is???  Any Ideas? ***EDIT***  IT was TokenFate.  Deleted that script and my API is back up.  Not sure why.

Sorry about that, that's my fault.&nbsp; Details here:&nbsp; <a href="https://app.roll20.net/forum/post/8566590/token-fate-on-click-broken#post-8570315" rel="nofollow">https://app.roll20.net/forum/post/8566590/token-fate-on-click-broken#post-8570315</a> TL;DR - it should be fixed on Tuesday or you can install the previous version.
