Layer error: reduce.median: Error in map(ID=20200526T144731_20200526T145503_T19LFJ): Element.copyProperties: The source parameter is required

Question

This code was working normally and now it's giving this error, does anyone know what changed?

https://code.earthengine.google.com/db01303623e6f1a4d0e417f1c3c0713e

The following errors appear:

Answer 1

I'm not sure what the specific issue it here, but in general, copyProperties can be avoided when you are scaling bands and wanting to retain the image's metadata by overwriting the original bands (set the overwrite parameter of ee.Image.addBands to true). Whenever possible, this is a better practice than copying properties. Your scaling function would be something like the following (untested).

var scaleData = function scaleBands(img){
  var refl = img.select('B.*').divide(10000);
  return img.addBands(refl, null, true).select('B.*|QA60');
};
