An issue in the custom application code or rules. The design assumption is to ensure that Pega produces the output to Facebook to always give some feedback to the user. If a particular request does not produce it, then an error occurs.
The answer mode for a question rule used in the flow was set to dropdown type, and hence the question displayed with a button for user interaction. This resulted in the error.
ResolutionPerform the following local-change:
