SyntaxError: Expected '}' (Edge) SyntaxError: missing } after property list (Firefox)
There is a mistake in the object initializer syntax somewhere. Might be in fact a missing curly bracket, but could also be a missing comma, for example. Also check if any closing curly brackets or parenthesis are in the correct order. Indenting or formatting the code a bit nicer might also help you to see through the jungle.
Oftentimes, there is a missing comma in your object initializer code:
var obj = { a: 1, b: { myProp: 2 } c: 3 };
Correct would be:
var obj = { a: 1, b: { myProp: 2 }, c: 3 };
