How to fix this Error Can’t Merge Flowvariable Stacks! (Likey Loop Problem)
You have two loop starts and no loop end here. That does not work. What would happen if one loop has more iterations than the other? You will need to merge the two tables going into the Chunk Loop Starts first into a single table, then loop over that. You can use a Joiner or, if the tables have always the same size and ordering, a Column Appender.
if you don’t mind, can you please share the workflow?
Sure, here’s an example: Loop Through File Pairs – KNIME Community Hub.
