Description

Describe what you were trying to get done.
I am trying using my watershed baoundry(.shp) ('users/gaowudao/hybas_lake_as_lev06_v1c') to get the image in the specific watershed.
Tell us what happened, what went wrong, and what you expected to happen.
The error"Number.multiply: Parameter 'left' is required" occured

What I Did

Paste the command(s) you ran and the output.

@gaowudao USDA NAIP images only cover the United States. Your watershed boundary is outside the US. Therefore, you won't get any NAIP imagery.
