Due to user error on my part the file that I uploaded to modules.openmrs.org was incorrectly named webservices.rest-2.17.omod.jar instead of webservices.rest-2.17.omod.
I have fixed the filename on modules.openmrs.org, but if you downloaded this prior to today, you would need to manually rename the filename to remove the “.jar” before adding it to OpenMRS.
