Problem with downloading images

Hi,
I am trying to download images from the API for SENTINEL2_L1C.
The problem is that sometimes I get an array of all zeros. I tried the same code on two consecutive days, On the first day some images were Ok but on the second day the images were all zeros.

Hi,

This behaviour does not sound unexpected as Sentinel-2 has a revisit time of 5 days, therefore, you are not going to return imagery on consecutive days. You can read more about the mission in our docs.
