<summary><mark style="color:yellow;">Warning:</mark> "Vehicle do not have model in vehicle properties"</summary>

If you're seeing this warning, it means that one or more vehicles assigned to you in your `owned_vehicles` or `player_vehicles` table do not have a model defined in the `vehicle`/`mods` column.

If the column is missing, it means your vehicle isn't being properly inserted by an external resource. Normally, a model should be present there. But don’t worry - in most cases, if you take the vehicle out of your garage and then put it back in again, the full vehicle properties will be saved correctly. In that case, there's nothing you need to worry about.

If you're using QB-Core, it's also possible that the vehicle model stored in `player_vehicles` does not exist in `qb-core/shared/vehicles.lua`. Remember that this file must include complete information about the vehicle, such as the price and model.
