5.5.0 RN Async error

[christhegrand]

I'm trying to upgrade to version 5.5.0. I'm getting this error in our iOS app on our login screen:

2019-10-11 16:48:28.117 [error][tid:com.facebook.react.AsyncLocalStorageQueue][RCTUtils.m:417] 
Error: {
    message = "Entries must be arrays of the form [key: string, value: string], got: (\n    \"{\\\"deviceId\\\":\\\"41ad874d-83d1-462f-a85a-bb8f72bb457aR\\\",\\\"userId\\\":null,\\\"optOut\\\":false,\\\"sessionId\\\":null,\\\"lastEventTime\\\":null,\\\"eventId\\\":0,\\\"identifyId\\\":0,\\\"sequenceNumber\\\":0}\"\n)";
}

Judging by this Github issue, it might be caused by one of the nulls in there combined with JSON.stringify being called from somewhere in amplitude.native.js?

I got same error when I amplitude.init(key) with wrong type of key(like number)

Ah, yeah, but null is a valid value for userId according to the Amplitude documentation:

"If you want to explicitly log users out or log events under an anonymous user, then you will need to set the User ID to null and regenerate a new Device ID. You can do this by following the instructions in our SDK documentation. Here is a link to our iOS documentation and here is a link to our Android documentation."

I have the same issue. Running logEvent without init isn't working. And it's a nice to have in development.
