Account template doesn't support JSON anymore

[Paul_vd_Dool]

I have adjusted the customers/account template before on the Dawn theme to support sections as I wanted to add an app extension to it.

But as of very recently, I suddenly get the message that the account template doesn't support JSON.

What's up with that?

Why this sudden change?

I've been working on an extension, and ran into that same error message last night while working with customers/account template.

The version of Dawn installed on my dev store by default shows 6.0.2 but the customers templates are all still liquid - they do not match what is in the current Dawn repo after the customer templates were JSONified - and it would not let me save json files in the theme editor.

This doesn't really answer your question about why we're getting that error message now, but I installed a new dev theme by cloning Dawn and the customers templates are all json now and work with app blocks.
