Hello. Knime workflow invocation guide describes the use of the Workflow service input node to create a bridge between call and callee workflows. In theory, 3 dots would be available to change the variable type received by node. However, I cannot see the 3 dots.
If I change to the old interface, the 3 dots appears. Anyone is having the same issue?
your observation is correct. Replacing ports as described in the documentation is not (yet) available in the new UI. Though, there is a rather straightforward way to get a suitable Workflow Service Input node.
Select the predecessor node
Drag&drop the output port to open the quick nodes adding panel
Search for the “Workflow Service Output” node
Add the node
Node is connected and added with the correct port.
