SMART reaction - RDKit one component reaction node

Dear KNIME users,

I would like to transform an ester to a carboxylic acid. I tried with RDKit one component reaction but without success...

When I tried this:


I just have a list of COOH but with a missing part of my molecules.

How can I solve this problem?

Thanks in advance.
