MOE descriptors node error - could not calculate descriptors

Hi,

after a recent upgrade of KNIME to v3.3 my workflow stopped working. Precisely, the MOE Descriptors node stopped working and is unable to claculate descriptors. At first was telling me that the molecules (which I convert from smiles to SDF (MDL SDfile)) do not have explicit hydrogens (workflow 1, below), which I’ve then added using standardizer node (workflow 2), but it still doesn’t let me compute the descriptors. Any ideas what may be causing the issue?

 

Worflow 1:

WARN  MOE Descriptors      0:2936:2129 RowID Row0 seems to have no explicit hydrogens. Please check.

Could not calculate descriptors for Row0

RowID Row1 seems to have no explicit hydrogens. Please check.

Could not calculate descriptors for Row1

RowID Row2 seems to have no explicit hydrogens. Please check.

Could not calculate descriptors for Row2

 

Workflow 2:

WARN  MOE Descriptors      0:2936:2129 Could not calculate descriptors for Row0

Could not calculate descriptors for Row1

Could not calculate descriptors for Row2

This is more a question for the vendor CCG, isn't it?

Possibly, I've sent them an email but I was wondering if anyone here had the same problem. If you find it inappropriate then delete the topic.
