Thank you for letting me know. I am getting the same error and have contacted TIDAL support.
In the meantime you should be able to use Audio Cast:
- play something in the TIDAL app
in BubbleUPnP:
- go into the 'Now Playing' tab
- tap the cast icon in the top bar
- tap the 'Audio Cast' icon for the renderer you want to play to
- grant the asked permissions
=> you should hear TIDAL playing on your renderer
