Hello, Is there a way to dynamically set a property in a change node? Something like: set flow.mode[msg.targetMode].enabled to msg.payload I know I can do it in javascript, but it would be better with a change node. Thank you Andy

This is possible with a jsonata expression ($eval) - here you can see an example:
