syntax error in Language.js

[yonatanlehman]

Hi
Flare is generating a file "language.js" which contains the following
define({'skin':{,'HTML5___Top_Navigation':{},'TopNav':{}},'toc':{}});

I'm getting a runtime error in the Chrome debugger

/docs/Data/Language.js?t=636642332693426216:1 Uncaught SyntaxError: Unexpected token ,
Looks like it's complaining about the comma between the "{" and 'HTML5 - and who can blame it ?

So two questions
1) what is this javascript file? What is it used for ?
2) How can I ensure that either it is not generated or that it is generated without a syntax error ?

Thanks
