Error using knime-bundled openbabel to convert InChI string to InChI keys

Hi guys,

I'm trying using knime-bundled openbabel to convert InChI string to InChI keys but I'm getting the following error:


ERROR OpenBabel Execute failed: Conversion failed: ==============================

*** Open Babel Warning in Init

Cannot open element.txt defaulting to compiled data.

==============================

*** Open Babel Warning in Init

Cannot open aromatic.txt defaulting to compiled data.

==============================

*** Open Babel Warning in Init

Cannot open atomtyp.txt defaulting to compiled data.

*** Error in `/usr/local/knime/knime-full_2.11.0/plugins/org.knime.ext.chem.openbabel.bin.linux.x86_64_2.3.1.0041615/linux/x86_64/babel': free(): invalid pointer: 0x00007fff6f21cdef ***

 

Other types of conversion (e.g. SMILES to InChI) work fine. Also if a local version of openbabel is used the node works fine. Anybody has an idea why this happens? I include an example workflow.
