Validation returns a missing_child error message.

Compulsory child element is missing

A component lacks a child element - the one named in the message - that is mandatory.

For example, a solicit must take one or more responses as its children.


  1. On the Canvas panel, select the component that contains the error.
  2. Click the icon beneath the solicit or request to give it the required child element.
    You also have to drop one or more fields on the response or the reply.
