Curious About Tiled Syntax Error

[TaylorN]

I get a syntax error

Uncaught SyntaxError: Unexpected token :

in the console when I load my tiled json maps. Everything runs fine, my maps are loaded correctly, but why does it give this error?

json looks like:

{ "height":32,
 "layers":[
        { "data":"AAAAAAAAAA"

etc.

 I understand that there's no var declared at the beginning of the object, but it's saved as a json file and loaded as a json file. Why give this error?

Just wondering.

Thanks,
