I noticed that the error no longer appears, which is nice. However, when a fetch depends on a param value being passed from a previous screen, something isn’t working. No text is displayed in live preview, while the screen appears to work in build.

Hey Gary,

Glad your original error isn’t appearing but sorry a new one is coming up now! We’re taking a look at this issue as well. I’ll let you know once we have a fix up.
