Hi, I am getting this error when trying to use multiSolidBodyMotionSolver to model a car with spinning wheels. I am using AMIs to rotate the spokes with rotating wall for the tires. I was able to run the simulation with the wheels set as walls without the AMIs. I also got moveDynamicMesh -checkAMI to run without any errors. I went to the scalarField files and checked out the lines that it references, but I can't figure out what it means.
Error: Code:

I just tried running the simulation with just one rotating zone and it did not work, so I think the issue is with something else. Ill add my case file here:
