Issue - To show the port output, please execute the selected node

I have download the sample workflow 1.1 - Simple OpenAI Prompt

then i input my open ai api key and try to run this workflow. everything is green, however after i execute my LLM prompter node i get this msg only and no results “To show the port output, please execute the selected node”.

Here is a screen recording of when i run my workflow: 5.1.0 Bug? - Feedback & Ideas / Implemented Fixes - KNIME Community Forum - Google Chrome - 12 August 2024 | Loom

Anyone can advise what am i missing out? thanks!
