NullPointerExceptions with custom path

[pikachyu]

Hi there,

I am getting NullPointer exceptions right after I start the bot. I have recorded a custom path, edited the class file to use this file (path_etc.json). I am in the same map as I recorded the path.

Log is filled with below;

[20:24:53 ERR] PerformAction on FollowRouteGoal
System.NullReferenceException: Object reference not set to an instance of an object.

Thanks!

What zone is this in ? I think it is a problem with it not matching the MapId correctly between these two: https://github.com/julianperrott/WowClassicGrindBot/blob/master/PathingAPI/WorldToMap/WorldMapArea.json and https://github.com/julianperrott/WowClassicGrindBot/blob/master/PathingAPI/WorldToMap/uimap.csv

Barrens seems to be the issue, works in the other areas.

Could you do the following command in the chat window and tell me what it says.

/dump C_Map.GetBestMapForUnit("player")

[1]=1413 I just noticed that player dot is missing from the map. 1413 is in the csv

I'm getting the same error message:

Also got [1]=1413 in Barrens.

Not sure how the mapping is performed, but something should be changed in WorldMapArea.json maybe?

I'll debug it this weekend, will create PR.

[julianperrott]

Should be fixed in the latest code.
