<summary><strong>[</strong><mark style="color:yellow;"><strong>WARNING</strong></mark><strong>] Ignoring vehicle </strong><mark style="color:blue;"><strong>model</strong></mark><strong> due to invalid Model</strong></summary>

If the vehicle model is available by default in GTA 5 and is on this list [(FiveM Vehicles Docs)](https://docs.fivem.net/docs/game-references/vehicle-models/) - it means you have an older build, you need to remove them vehicles from the `vehicles` table in the database and from `config.lua` or [update the game build](https://docs.fivem.net/docs/server-manual/server-commands/#sv_enforcegamebuild-build).\
\
If it's a custom model, it means that this vehicle can't be loaded correctly, in this case, you need to remove the vehicle from the files or repair the model.

If the vehicle is not available on your server, it might not have been started properly. Also, if it's a **vanilla GTA vehicle**, your **game build** might be outdated.
