SNAP 8 error when starting the biophysical processor

Hello everyone,
i just installed SNAP 8
I downloaded a Sentinel-2 level 2A image from schihub
I loaded the (unzipped) image into SNAP 8
I started the geometric resampling
then starting the biophysical processor I have the error shown in the attached figure ion

This procedure was successful in SNAP 7.0, so it now appears not to work in SNAP 8.
What could be the problem?

Hi @safalabolo,

I am trying to reproduce the error, how have you resampled? To 10m or 20m? Could you post a screenshot of the resample operator configuration? It was a full product or a subset?

Also which Biophysical operator have you used?

Thank you in advance,
Martino

EDIT: I tried to reproduce the error in my machine:

S2A 2A unziped Product => Geometric Resample to 20m => BioPhysical Operator LAI index

And it worked without problem.

Hi Martino,
thank you. I was able to overcome the problem by reinstalling SNAP 8.
Thanks so much for the support.
