Probleme with drift counter

Hello,

I use this counter ([Release] Drift Counter) and I have an error:

Error running system event handling function for resource DriftCounter: citizen: /scripting/lua/scheduler.lua: 41: Failed to execute thread: driftcounter_s.lua: 66: attempt to index a nil value (local ‘data’)

Since I start programming I try to read the code but I have not found where it can come from.

If there would be a charitable soul to help me
