Review Comment:
Your query does not fail for me.
The fix is in
```
public Expr transform(ExprFunctionOp funcOp, ExprList args, Op opArg)
{
Element el2 = ElementTransformer.transform(funcOp.getElement(),
transform, this);
}
```
So the issue is related to (NOT) EXISTS *within* in a subquery.
Also note that, the transform is an `ElementTransform` - so `SELECT * { ?s a
?c }` is treated different than `?s a ?c` - although the Op would be the same.
I reduced the query to this:
```
SELECT ?s {
SELECT ?s {
?s a ?t
FILTER EXISTS { SELECT * { ?s a ?c } }
}
}
```
