I’ve got a workflow that takes a table with ~20,000 SDF molecular structures (one per row) and converts these to PNG images using the ‘Renderer to Image’ node (using the Marvin renderer). This has worked successfully for several years but recently the node has been failing and returning the following error:
“Execute failed: (“NullPointerException”): null”
I’ve ensured that there are no cells with missing data so that doesn’t seem to be the problem. Does anyone have an idea of how to resolve this?
Thanks in advance,
