Failed export of images without specified region

[Zaubatrix]

Hello everybody,

my export task fail when I do not specify a region in the export statement. If I do everything runs fine. As help tells me region default is set to the image's region. For a global dataset. I would assume I do would get a global image as an output (which is what I want). I tested this with quite a variety of Image Collections by now, with the same result.

Best Regards Hannes
