Ocean data disappears with "Terrain Correction"

snap
1

Dear all,

I am using SNAP10.0 for preprocessing.
I understand that setting “nodataValueAtSea” to “True” will delete sea surface data.
Therefore, I coded it as follows.
This code(snappy) works as expected on Windows 10.
However, on Ubuntu 22.04, the sea data disappears.
It seems that “nodataValueAtSea” does not work on Linux.

parameters = HashMap()
parameters.put('demName', 'SRTM 3Sec')
parameters.put('nodataValueAtSea',False)
parameters.put('pixelSpacingInMeter', 10.0)
parameters.put('sourceBands', 'Sigma0_VV')
product = GPF.createProduct("Terrain-Correction", parameters,product)

Any help would be appreciated.
All the best,

Zuiko

I’ve noticed a number of errors occurring on startup.
Could these be related?
