The child is async so you should have a valid callback function here. Instead of continuing to do the broken callback handling outside of the API (i.e., rctx->complete) please use the API mechanism that is provided for this purpose. > In the current implementation, the inner algorithm is called directly, and we > use the outer algorithm's callback.

Probably I can add a comment before > the set callback function.. will this be ok?
