Problem with Patrol script

I have been using the Patrol (Waypointpatrol) successfully, but suddenly it has started throwing an error in one game, but not in another... this is in response to clicking the 'Path' button. For reference, the error message generated was: TypeError: Cannot read property 'get' of undefined TypeError: Cannot read property 'get' of undefined at Object.WPP.ShowPatrolPaths (apiscript.js:2812:15) at Object.WPP.AddPatrolPath (apiscript.js:2734:30) at apiscript.js:3082:23 at eval (eval at <anonymous> (/home/node/d20-api-server/api.js:143:34), <anonymous>:65:16) at Object.publish (eval at <anonymous> (/home/node/d20-api-server/api.js:143:34), <anonymous>:70:8) at /home/node/d20-api-server/api.js:1393:12 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 Ld.Mb (/home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:94:425) at /home/node/d20-api-server/node_modules/firebase/lib/firebase-node.js:111:400 I've double checked I am using all the same scripts in both games.  And a previous page where had used it still worked, only it now wouldnt display the paths even tho the tokens were following them. So I deleted that page in case it was having an effect, but no luck. Any assist is appreciated as I really like the script for pre-encounter flavour.
Further research, if I remove ChatSetAttr script I get: 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: SyntaxError: Unexpected token var So maybe something in that macro is causing a conflict?  But I use it in my other game without issue?

Try adding a semicolon to the end if each script in its own line. Sometimes codes interfere with each other, and the semi colon will make sure there's a cleen break between them
Did that, got rid of the second error, but not sure which one it was, however Patrols still refuses to work in the one game, but not the other.

Do you have all the dependant scripts installed in the non-functional campaign?
Yes. The patrol script had worked, as I mentioned. And it works in my other game which I have copied from to try to make it identical.  I can just not use it for now and see if things change with time... that has worked before.
I copied the campaign and reloaded everything, and it works fine.  Not sure what sort of campaign things you can corrupt but that must be what it is...

Well, I'm unsure, but I'm very glad you got it working. Sorry I couldn't help more!

The issue is that you deleted a page that had paths on it and the pageid for that page persists in the state.  When you try to show paths, it creates those paths on that deleted page (which fails) and then tries to access them. Here's a version of the script that will fix that issue on startup: state.WaypointPatrol = state.WaypointPatrol || {'PatrolStatus': true}; var WPP = {}; WPP.Command        = '!wp'; WPP.SpeakAs        = 'Patrol'; WPP.RefreshRate    = 5;    // in seconds, minimum 1 WPP.RetainLastMove = true;  //save patrol moves as lastmove WPP.ShowPaths      = true;  //refresh visible paths on add or delete WPP.AddPatrolPath = function(selected, patrolname) {     //make sure the patrol name is provided     if (!patrolname || patrolname.trim() === '' ) { return 'Err: patrol name missing'; }     patrolname = patrolname.toLowerCase();     //verify only one token is selected     if (!selected) { return 'Err: no token selected'; }     if (selected.length !== 1) { return 'Err: multiple tokens selected'; }     if (!selected[0]['_type'] || selected[0]['_type'] !== 'graphic') { return 'Err: selected must be a graphic'; }     //get the token object     var token = getObj('graphic', selected[0]['_id']);     if (!token) { return 'Err: token not found'; }     //read the patrol path from token's last move     var lastmove = token.get('lastmove');      if (lastmove === '') { return 'Err: token missing last move'; }      lastmove = lastmove.split(',');     var pts = [];     while(lastmove.length > 0) {         pts.push({             'left': +lastmove.shift(),             'top' : +lastmove.shift(),         });     }     pts.push({         'left': token.get('left'),         'top' : token.get('top'),     });     //add patrol path to state if it doesn't already exist     var pageid = token.get('_pageid');     if (!state.WaypointPatrol['paths']) { state.WaypointPatrol['paths'] = {}; }     if (!state.WaypointPatrol['paths'][pageid]) { state.WaypointPatrol['paths'][pageid] = {};
