I called CreateGroupFromTensor[cXt[ua]] after calling DefineTensor[cXt] and then erroneously using cXt without indices (i.e. as scalar). I then received the error message:
Exception:
"CreateGroupFromTensor: Not a tensor"
If[TensorIndex["a", "l"] == TensorIndex["b", "l"] == Null, name$322, name$322[indices$322]]
which is unclear. The error message should say that it is about cXt, and that cXt[ua] was not of the expected tensor kind.
