ERROR TypeError: Cannot read property 'initializeJSI' of null, js engine: hermes #1797

Closed oushima closed 4 months ago

oushima commented 4 months ago

Hello,

I am using WatermelonDB + Expo + React-Native. I can't seem to figure out how to solve this. Could someone please help me?

I am encountering this error when I use Expo Go build on my iPhone 14 Pro. If I run it as Developer Build with an iOS emulator on my MacBook Pro, then it works fine.

Thank you in advance. Kind regards.

Yea WatermelonDB won't work with expo go, only development builds. The error you are getting isn't a bug its just how expo works. Something to do with native modules not being support in expo go I believe.

Ah okay, I got it. Thank you!
