[ERROR] gamemodes/darkrp/gamemode/modules/base/sv_gamemode_functions.lua:740: attempt to index local 'jobTable' (a nil value)
These errors may appear in the web console or in the in-game console. It's advised you check both.
FPtje has kindly provided an online Lua script checker. This will provide you with more accurate errors in the job code - allowing you to make a more focused attempt at correcting the errors. This can be accessed here: Script Checker
If you're struggling to debug the job using the FPtje's Script Checker then it is advised that you remove the job that is causing the error and recreate it using: cSite's Job Generator
Please refer to our this article for help with recreating the job: Adding Jobs In DarkRP
