booleanBodies failure --

alan_1

My use of booleanBodies() is failing.  I think I am providing valid parameters.
Here's the code snippet.

            var asdf1 = evaluateQuery(context, qCreatedBy(A, EntityType.BODY));

            var asdf2 = evaluateQuery(context, qCreatedBy(B, EntityType.BODY));

            booleanBodies( context, id + ("boolean" ~ index), {

                    "tools" : qCreatedBy(A, EntityType.BODY),

                    "targets" : qCreatedBy(B, EntityType.BODY),

                    "operationType" : BooleanOperationType.SUBTRACTION

            });

An error is thrown at line 73 of feature.fs (version 376.0).

                if (!isTopLevelId(id))

                    throw error; // rethrow

The two bodies are real bodies and they do intersect at a non-zero volume.  Neither is entirely within the other.
The reason for the two "asdf" variables is to prove that the qCreatedBy() queries are valid.
Any idea what I might be doing wrong?

A bit more context is needed to diagnose this -- even if the two bodies intersect in non-zero volume, their difference may still result in non-manifold (zero-thickness) geometry, which would cause the boolean to fail.  A link to a public document reproducing the problem should make it possible to diagnose.
