Error "LaunchDarkly SDK already initialized" React Native SDK

Affected: React Native SDK client-side <10.x

Symptoms

React Native SDK <10.x had some limitations on reloading React's native modules. In some cases performing a hot reload throws an error indicating that the LaunchDarkly SDK is already initialized. 

LaunchDarkly SDK already initialized

Cause

The hot reloading is not fully supported by the React Native SDK <10.x. Specifically, the hot reloading behavior of the React Native SDK does not automatically reload React's native modules. 

Solution

It is safe to catch this error and proceed; however, you must decide whether that is an appropriate behavior in your application.

Here's how:

let ldClient = new LDClient();
try {
    await ldClient.configure(config, context);
} catch (err) {
    console.log(err);
}
