AEM - How to accommodate one component inside another component in AEM without having errors in m.json

[#1]

I am in the midst of creating one page contains customer issue registration process. here I have two components, say: 1. Customer-Issue component and 2. Customer-care-Call component

the 2nd component to be placed to the right side side of the first component. I already completed with this thing. But am getting some error while generating page.m.json

How we can accommodate one component inside another component?

Are you using a layout container to organize your content. You should be using a grid that lets you drop in the inner components to organize these.

You can organize these components using a two column layout.

Here are the details how to use the layout (aka - Reponsive Grid) in AEM.

Getting Started with AEM Sites Part 3 - Client-Side Libraries and Responsive Grid

You should be following that approach.

The css part is already given. I can't edit that. So from the page level, how can I accommodate the things as given in the picture above?

Thanks In Advance..!
