API Error in Sandbox

Your scripts are currently disabled due to an error that was detected. Please make appropriate changes to your scripts and click the "Save Script" button and we'll attempt to start running them again. More info... For reference, the error message generated was: Error: Firebase.update failed: First argument contains NaN in property 'current' Error: Firebase.update failed: First argument contains NaN in property 'current' at Ba (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:9:186) at Ba (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:10:207) at Aa (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:8:462) at Ea (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:10:403) at J.update (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:146:318) at TrackedObj._doSave (/home/node/d20-api-server/api.js:766:27) at Timeout.later [as _onTimeout] (/home/node/d20-api-server/node_modules/underscore/underscore.js:828:25) at ontimeout (timers.js:380:14) at tryOnTimeout (timers.js:244:5) at Timer.listOnTimeout (timers.js:214:5) Any ideas?  I have been getting this error for about two days.  I don't have the slightest idea what it means.
Without knowing what scripts you're using, it's nigh impossible to tell what your problem is, but I can take a guess that one of your attributes on a token or character is not a number (NaN) and one of your scripts is looking for a number and failed without catching that error. Disable all your api scripts and restart them one at a time until you get that error again and you'll know which script is the problem.

Slight refinement on what HB (Sky) said:  One of the scripts you have just updated an Attribute's current property, but whatever it tried to put in it evaluated to NaN.  Firebase does not accept NaN as a value and throws that exception when it tries to persist the API script's change into the Firebase storage for that game.   If you have a list of the scripts you have installed, we might be able to infer which ones are likely to have caused the issue.
I have found that I most often get this error when I use the parseInt function for a value that does not meet the requirements of parseInt. For example "text1" would result in NaN whereas "1text" would result in 1. If you use parseInt and you don't know if the text you are passing will match you could do parseInt(variableName||0) which will default the result to 0 unless it can parse the first value.

Actually: parseInt(variableName,10) || 0 Non-zero length text is truthy, so putting the || inside the call will only catch empty text. You're right, that is the most common way to get NaN.
I used the XP script and put a bad syntax in and it returned a value of NaN in the chat, but the scripts were shutting down before I ever tried that.  I kept restarting it during my game last night and they would shut down within a few minutes.  Then towards the end I did the XP thing and it was working so I tried adding XP to one character with !xp challenge @{selected|token_id} and that's where the NaN thing came from.  I do not remember what the script error messages were before that as I didn't pay much attention.

Hmm, gonna have to put in gating to stop that NaN from happening. Adding it to my EasyExperience todo list.

The 5E Shaped trap theme's script is deprecated but it's functionality still exists with the new 5E Generic trap theme. Install the 5E Generic trap theme and on its script options page, set the "sheet" option to "shaped" and that should work fine again.

The Aaron said: Actually: parseInt(variableName,10) || 0 Non-zero length text is truthy, so putting the || inside the call will only catch empty text. You're right, that is the most common way to get NaN. NaN also comes from Math functions failing (eg, Math.sqrt(-1) ). Invalid mathematical operations also produce NaN (eg, 'foo' / 100 ). Really, it's anything that ought to be a number and isn't. Hence Not a Number. =) Or, since NaN !== NaN , you might say it's Not a NaN. ~_^
