To get a value passed to the node after execution use the following:

mynode.py

    def execute(self, inp0):
        result = inp0.reverse()
        return { "ui": { "input": inp0 }, "result": result }

mynode.js

	async nodeCreated(node)
	{
		if (node.comfyClass === "MyNode")
		{
			node.onExecuted = function (ui)
			{
			    console.log(ui.input)
			}
		}
	}

note that if you use OUTPUT_IS_LIST = (True,) you might want to put the ui message into a unit list, otherwise it's interpreted as an array (i.e. an array of characters for strings).

mynode.py

	RETURN_NAMES   	= ("out0",)
	RETURN_TYPES   	= ("STRING",)
	OUTPUT_IS_LIST 	= (True,)

    def execute(self, inp0):
        result = [v.reverse() for v in inp0]
        return { "ui": { "input": [inp0] }, "result": ] }
