Data load error in overview page cards upon using guided development

[shekhar01]

I am facing an error upon using fiori guided development. 

In VSCode, upon using guided development, if the new card fails to show data due to incorrect data binding or error 50014 then there is a constant error which prevents loading of data in other cards. 

At the current moment I am using git reset --hard to remove all modifications after the previous commit to load data normally. I want to know the cause of this because the code looks same, as there will be modifications in manifest.json and annotation.xml only.

Code used for cards are provided for reference.

change is edmx:Edmx to Edmx. It is everywhere on the annotation page. Guided development is making changes in whole document instead of adding cards. Still, a good reference for cards with codes is preferred.
