ERROR: MethodError: no method matching validate_atomic_array_key(::Symbol)
The function `validate_atomic_array_key` exists, but no method is defined for this combination of argument types.

Closest candidates are:
  validate_atomic_array_key(::SymbolicUtils.BasicSymbolicImpl.var"typeof(BasicSymbolicImpl)"{SymReal})
