I think the problem with this version here is `VectorDomain(8,lower=[0,0,0,0,-Inf,-Inf,-Inf,-Inf])`. Could you please try this version with something like `VectorDomain(8,lower=[0,0,0,0,-1e6,-1e6,-1e6,-1e6])` or alternatively `VectorDomain(8,lower=[0,0,0,0,-Pumas.∞,-Pumas.∞,-Pumas.∞,-Pumas.∞])`? Using `Inf` in the bounds causes `Inf` to propagate through the computations causing the error you are getting.
