Sometime I get this error. Could you plz explain in which case we get this error?.
Because this issue does not have any callback, so front-end just wait here forever, do we need a callback/event/delegate for this thing?

This generally means that the method called by JS has no corresponding processing logic on the Swift side.

U can check if the handlerName is registered correctly on swift side, and U can also debug the JS code by referring to this article.
