[Help] I keep getting the "TypeError: Cannot read property 'id' of undefined" Error

So I have been getting this error for a couple of games now and it completely crashes the API Sandbox. I saw another Post that said it was the Combat Tracker Script so I removed that and now use CombatMaster but it still happened. Can anyone help me here? Error : TypeError: Cannot read property 'id' of undefined TypeError: Cannot read property 'id' of undefined at showHelp (apiscript.js:51650:82) at commandHandler (apiscript.js:48023:7) at apiscript.js:47750:25 at Function.each (/home/node/d20-api-server/node_modules/underscore/underscore.js:1310:9) at inputHandler (apiscript.js:47745:23) at eval (eval at <anonymous> (/home/node/d20-api-server/api.js:154:1), <anonymous>:65:16) at Object.publish (eval at <anonymous> (/home/node/d20-api-server/api.js:154:1), <anonymous>:70:8) at /home/node/d20-api-server/api.js:1662:12 at /home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:93:560 at hc (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:39:147) And here are my Scripts:

I suggest you try to narrow down which is the cause, by turning off one at a time and checking if the error continues.

This is the line causing the issue in CombatMaster: makeAndSendMenu(`&lt;a href="<a href="http://journal.roll20.net/handout/${handout[0].id}&quot;&gt;View" rel="nofollow">http://journal.roll20.net/handout/${handout[0].id}"&gt;View</a> Help&lt;/a&gt;`,title,'gm') The issue is that findHandout() is failing to find what it expects, and returns an empty array: findHandout = function (title) { let handout = findObjs({_type:'handout', name:title}) return handout }, The fix would be to either return an empty object that behaves like a roll20 handout, or create a handout by that name to return, or handle missing handouts explicitly.

Thank you! I will try to create a handout with the name "title" then and see if that works.

title is a variable, it contains the name of one of the help handouts created by CombatMaster.&nbsp; I sent a message to Vic about this, maybe he can patch it to recreate the handout if it's missing. Did you delete some handouts created by the script?&nbsp; That would likely cause this to happen.

Did you delete some handouts created by the script?&nbsp; That would likely cause this to happen. No I freshly installed it, perhaps it wasn't done setting up when I ran one of the commands, I will test to see if it created the Handout in the meantime, maybe the error is gone now.

i had the same thing and it's definitely a timing issue as it takes some time for CM to create all handouts. Once CM has created the handouts it won't happen again.The creation - if needed - only starts after a second after API startup and each of 16 handouts requires two calls with measurable duration. It definitely possible to request help too early - and when you do that the API sandbox crashes and you can end up with a few empty handouts.&nbsp;
