DXA: AbstractController - Region not found on page: Social

Question

I have added new Component Templates that will render on two new Regions created under a generic module that was created exclusively for our website entiry, Region and Page separate from the core views.

I have published the settings and the new region appears in the regions.json file as

{"Region":"Generic:Social","ComponentTypes":[{"Schema":"tcm:3-151-8","Template":"tcm:3-522-32"}]},

The name of region mentioned in metadata of template is also the same. the region Social.jsp has just one entry:

<tri:entities region="Generic:Social"/>

When I run the Page I get the following error:

A problem occurred while rendering this section

The logs show:

Answer 1

The prefix to your Region name defines the Module name, and also specifies where DXA will search for the region view. All views for a certain module must be placed in an Area by that same name.

In your case Generic:Social defines that you must have a Module named General and a view named Social which should be in an Area named General.

Since you mention in the comments it is working when you move the views in a folder named Core, it sounds like you have some misconfiguration somewhere in your Module and the location of your views. Moving everything to the Core module and Core area is not really the solution, that sounds more like a workaround ignoring the actual misconfiguration issue.
