Hi, unfortunately this is not something many here will be able to help with. From the look of that info, it is a Home Assistant initialisation problem (nothing at all to do with node-red I'm afraid)

As a courtesy, a quick search of ...

... reveals many results and most answers say "did you set credential secret"

So perhaps you didnt follow the instructions?
