Your arrow function is not syntactically correct (that is why the console is showing an error). I think when you want to return an object in an arrow function you have to nest the object in an extra pair of curly braces and use an explicit return statement. (Or wrap the object literal in parentheses)

So something like this:

map((element) => { return { key: value}; });

Or

map(element => ({key:value}));
