image works fine in emulator throws exception on the watch

The following code works fine in the emulator.

g.drawImage(atob("GBjCAP////+rStqvAAAAAA­AAAAAqqAAAAAKv+oAAACtVV+gAAKVVXvoAApVV6/­6AAlVXv/+AC1VXv6/gCVVVvu/gKValqnroLt7pfV­V4L5vpVVV4LtulVX14LquVX6p4K6+lar5oC//te/­tgC//5Xq3gAv/pVdWAAr/tVVaAAK/lVVoAACvlVe­gAAAKv+oAAAAAqqAAAAAAAAAAA"),40,40);

But when I try to load it as a clock face for multiclock it fails.

(() => {
  
  function getFace(){
    
    function draw() {
      g.reset();      g.drawImage(atob("GBjCAP////+rStqvAAAAAA­AAAAAqqAAAAAKv+oAAACtVV+gAAKVVXvoAApVV6/­6AAlVXv/+AC1VXv6/gCVVVvu/gKValqnroLt7pfV­V4L5vpVVV4LtulVX14LquVX6p4K6+lar5oC//te/­tgC//5Xq3gAv/pVdWAAr/tVVaAAK/lVVoAACvlVe­gAAAKv+oAAAAAqqAAAAAAAAAAA"),40,40);
    }

    return {init:draw};
  }

  return getFace;

})();

the error message I get is:

Uncaught Error: Expecting first argument to a valid Image

Any ideas what I am doing wrong ?
