What's this Error with n.animate() - Cannot read property 'from' of undefined?

[applefarm]

Can you tell me why I get this error `snap.svg-min.js?ver=1547965643:20 Uncaught TypeError: Cannot read property 'from' of undefined with:

 var n = Snap("#fan_back");
			console.log('here = ' + s + set);
			console.log('selector = ' + n );
			var n_bbox = n.getBBox();
			console.log('boxxxxx = ' + n_bbox.x + 'yyyy= ' + n_bbox.y);
			n.animate({transform: 't0,200'}, 5000, mina.backout, function () { n.animate({transform: 't0,0'}, 5000, mina.backin) }); 

console output:`

Thanks for any help

Have you tried with a different version of Snap (0.5.2 on the dev branch or 0.4.1) out of interest ?
