[mobx] Encountered an uncaught exception that was thrown by a reaction or observer component, in: 'Reaction[Reaction@1]' Error: [serializr] Failed to find default schema for undefined

[seunlanlege]

yeah I think this has to do with react-native v0.59.9

@shenopkss i was able to solve my issue by changing to @persist to @persist(type). it seems for all non primitives, you must now declare the type when using this latest version of mobx-persist. in my case one was an object and another an array that was causing my issues. changing to @persist('array') and @persist('object') respectively, solved my issue. hope it helps.

and its stopped working again, and i am not sure why :/

[clauderobi]

Same thing here.

And I am using @persist('number') for my 3 items I want to persist.
