[iOs] [remote debugging] Unable to find module for EventDispatcher React Native

See original GitHub issue

Goals

I’m trying to code normally. I just installed realm, it works great. But on iOs, after enabling remote debugging and hit reload, this error message pops up. It happens with both chrome debugger and React Native Debugger. It happens only on iOs.

Expected Results

I should see my app.

I was also having this issue and solved it by downgrading to RN 0.57.8. This obviously isn’t an ideal solution, but there really are no ideal solutions when it comes to using realm with a chrome based debugger (see #491). You’ll either need to accept limited debugging capabilities or switch to an alternative database.
