I mean the actual commit on github.

@dkayiwa it is at RESTWS-764 by tendomart · Pull Request #475 · openmrs/openmrs-module-webservices.rest · GitHub

The problem comes from your implementation of getByUniqueId(). You are passing a non numeric value to getTaskById() which expects an integer.

Why are you calling parseInt for a uuid which is a string?
