Hello Fabrizio,
It seems related to:
for which 2 tickets were opened:
https://senbox.atlassian.net/browse/SIITBX-441
https://senbox.atlassian.net/browse/SNAP-1400
I remember the error you get, it is corrected now. The data is not correctly written in the medatada (extra spaces that don’t respect the format), this is why SNAP throws an error. The handling was updated in order to ignore the extra spaces.
