I’m quite new to NODE Custom development. This is my experiment, I started to make my custom node which behavior similar to MongoDB Connector. My custom node had an output port containing ConnectionId.
When deploy to KNIME AP try to use it to connect with the existing KNIME node (KNIME Reader). I got a warning message “MongoDB Reader - Incompatible port spec, expected: MongoDBConnectionPortObjectSpec, actual: CiracorePortObjectSpec”.
I didn’t 100% understand Node Development. What should I do to fix this ?
