Thank you for your reply.
The Knime server version is 4.5.2.
The Phyton version in the server is 2.X and on the desktop l2.7.13 and 3.6.5
The server is managed by a different team within the Company.
I can’t attach the workflow as it is very complicated. I created an internal Interface to query Scopus data (Scopus is the largest abstract and citation database of peer-reviewed literature: scientific journals, books and conference proceedings).
I can send you part of the workflow in a screen shot in a private message if that can help.
