getting error message while loading addon

so i have attempted to add a vehicle add on using the alba method, i added the meta and carvariations files and all came out working fine. i load gta v and get lspdfr running, works fine. However when i try to spawn the car i added on it says" invalid model with hash 0xab7c8500". i go into my files and double check that the meta and car variations match up and they do. the car came from the this pack which did not have any meta files so i used standard ones and changed what needed to be changed. i also switched my game config up to the limitless add ons thinking that was the problem. Yet t still wont load the model i tried to add. any suggestions?
