JSON preview is not working in Chrome Dev Tools

Question

I have just updated my chrome to Version 61.0.3163.100 and it stopped formatting JSON data in network preview tab in Dev tools.

Chrome is now showing plain string for JSON.

So is this a bug in new version or have they added some configuration for it which is turned off?

After much research, it looks like this was a new feature added to Chrome Dev Tools.

You can get around it on your own development server by making sure your Content Type on your Response Headers is set to 'application/json':

Content-Type:application/json

This fixed the problem for me.
