Problem opening Sentinel-3 OLCI EFR

First of all, congrats for the release of SNAP 14. It looks promising.
However, when I try to open an OLCI product I get an error.

This is the exception:

Hi Marco,

you hit a spot that we never encountered - although we’re processing OLCI L1 systematically.

The reason for the crash is: in baseline version 003.00.00 the frame_offset is an 8 bit array, in 003.03.00 also, in 003.03.01 it is a 16 bit vector and finally from version 003.03.02 and onwards it is again an 8 bit array.

We are currently investigating with the OPT-MPC about this and the missing documentation on the sub-baseline version increments.

We will release a module update once we’re aligned with ESA.

Cheers,

Tom

Oh, what a mess. Thanks for the info Tom.
That’s not that important to me. I noticed it just by chance.

Ciao
