Coveo facets error

So, you are on September release of coveo components and you do not have tab component on your search view.  You now want to add coveo facet or the view, which was added fine, but the facet though indexed and pointing to correct field, it would either not render fine on view, what would you do ??? 

I tried doing the below…

• Checked conside and tried to debug error 
•  Actual Error – ‘Value can not be null or empty ‘ 
• What value is coveo asserting for ?checked call stack,  nothing important is missing 
• Checked Presentation Details and ensured that everything is set correctly. 
• Dropped facet component , no error any more …??
• Slack conversation with Coveo team , no break through!!!! They asked to check if I am not hard coding ‘Model .ID’ like plain text, but, nope we were doing things the correct way. 

What else ??? Google should have been my first resort, but I like to do basic checks first, seems like I should follow the reverse order. 

Found below link and seemed very much related, so gave it a shot.  That’s it!!!

It started working. Yippeeee!

Hope, this would help some one battling this issue and unaware that it is a known issue on September release.
