Undefined error when evaluating 'this.modelClass.associations'

See original GitHub issue

We have an app in production which uses the watermelonDb version 0.14.0. Recently we have been getting this error in our Sentry crash reporting:

TypeError: undefined is not an object (evaluating 'this.modelClass.associations')

This generally happens when making queries to the database.

We haven’t been able to replicate the issue locally but according to the crash reports it seems to be only affecting Android devices.

If anyone can offer any insight into this issue that would be great. Thanks

Since upgrading our app to React Native version 0.60.5 and watermelon db to version 0.15.0 we have not experienced this issue.

Same here, stopped seeing this error after upgrading to RN v0.62.2. But now we are seeing React Native’s “Should not already be working.” at almost the same frequency. So it looks like the error just mutated. Just asking here if anyone of you are also seeing it in your error logs? https://github.com/facebook/react-native/issues/28948
