Errors when loading a game built in CDK

I have an issue where 2 maps I built in the CDK are throwing the same error when I load it up in War Thunder. I’ve tried War Thunder support but they just keep referring me back to the forums after stating they do not support the CDK.
Not sure what is causing it as other maps I have built are not giving me this error. Hoping someone here can help me. TIA
