Biophysical parameter calculation

Optical Toolbox Sentinel 2 Problem Reports
#1

Hi everyone,
My question is about the biophysical parameter.
I want to extract biophysical parameters at 10m resolution. For this, I use the “Sentinel-2 Seper Resolution” plugin in SNAP and downscale the resolution of the 60 and 20m to 10m. When I want to calculate the biophysical parameters, this error appears to me (attached screenshot).

How can I solve it?
Thanks

first you need to resample the sentinel image and then subset using band 2, 3 4 and 8
