TypeError: Cannot read property 'get' of undefined Concentration API

I am getting this error when I cast a concentration spell. TypeError: Cannot read property 'get' of undefined at handleConcentrationSpellCast (apiscript.js:5557:89) at handleInput (apiscript.js:5426:13) at eval (eval at <anonymous> (/home/node/d20-api-server/api.js:168:1), <anonymous>:65:16) at Object.publish (eval at <anonymous> (/home/node/d20-api-server/api.js:168:1), <anonymous>:70:8) at /home/node/d20-api-server/api.js:1736:12 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) at Kd (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:93:546) at Id.Mb (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:93:489) at Zd.Ld.Mb (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:94:425) Here are the scripts I am currently running with it, and below is the macro I use to select haste from.

Do you have any non-word characters in your character name? If so, try removing them so you only have letters and see if it works. Also, is this for a player character or for NPCs? The script won't work for NPC's unless their character name is set to display on templates. It should work for PC's regardless of the setting. When you type @{selected|charname_output} into chat, do you get charname=<yourNameHere> ? If it doesn't look like that with your character name spelled correctly, try toggling the name display setting on the settings tab, it might have somehow got a bad value in it. I'm pretty sure this is the part that's failing:         let character_name = msg . content . match ( /charname= ([^ \n{} ] * [^ "\n{} ]) / );                     character_name = RegExp . $1 ;             characterid = findObjs ({ name : character_name , _type : 'character' }). shift (). get ( 'id' ), If it can't find the string 'charname=', or if the part it grabs afterwards isn't you character name, the findObjs() will fail. One last option is that it's finding too much after charname. If you've got anything attached to the end of the spell macro that follows on from the charname part and isn't a standard {{ template }} property, it might be getting bundled up with the character name.

Thank you, I didn't have the show template ticked, and had a few spelling issues around case sensitivity, but it seems to be working for my NPCs now. Thanks
