Hello everyone, I am developing a restful API that deserves some services to a front end module using OpenMRS rest API. For example, I have two Classes [Region](https://github.com/savicsorg/openmrs-module-savicsgmao/blob/master/api/src/main/java/org/openmrs/module/savicsgmao/api/entity/District.java) and [District](https://github.com/savicsorg/openmrs-module-savicsgmao/blob/master/api/src/main/java/org/openmrs/module/savicsgmao/api/entity/District.java), where one class (District) contains an attribute linked to the other. When attempting to get the list of District using rest API, I got this [error](https://pastebin.com/rB5trkhG). Here is the [RequestResource](https://github.com/savicsorg/openmrs-module-savicsgmao/blob/master/omod/src/main/java/org/openmrs/module/savicsgmao/web/resource/DistrictRequestResource.java) of my classes.

Please could some one can help on this?. Thanks

you would create Resources for both the entity data models and then [this property](https://github.com/savicsorg/openmrs-module-savicsgmao/blob/master/omod/src/main/java/org/openmrs/module/savicsgmao/web/resource/DistrictRequestResource.java#L44) would reference the resource Representation of the other **Region Resource**

like

`description.addProperty("region" , Representation.DEFAULT);`

instead of

`description.addProperty("region");`

the latter applies to a primitive data types not an entity model
