snapML custom data array as input

Hi,

 I'm trying to use a custom data array (as opposed to a texture) as input to my model.

My model expects 256x256 1 channel grayscale image as input.

 I did

var input = mlComponent.getInput("input.1");

input.data=data

"data" has my image pixels array ([0,0,255,0,0......]) which is 256x256 long.

I tried both 1D or 2D but I alwasy get the error

23:44:02.134 [Scenarium] Error: Argument 0: Value is not an array
at [anon] () native strict preventsyield
at onLoadingFinished (Script.js:382) preventsyield

thanks
