Error: Exception in HostFunction: Cannot set the logger factory after creating the sync client

[mednche]

How frequently does the bug occur?

Always

Description

I cannot seem to be able to use Realm.App.Sync.setLogLevel() or Realm.App.Sync.setLogger() in my react native app.

If I place Realm.App.Sync.setLogger() BEFORE const app = new Realm.App(appConfig); I get:
"Error: Exception in HostFunction: app must be of type 'object', got (undefined)". This makes sense to me, as app has not be defined yet.

If I place it straight AFTER const app = new Realm.App(appConfig);, I get:
"Error: Exception in HostFunction: Cannot set the logger factory after creating the sync client". Why am I getting this?

Always

Reproduction Steps

const appConfig = {
    id: appId,
    timeout: 10000,
    app: {
      name: "default",
      version: "0",
    },
  };

Realm.App.Sync.setLogLevel(app, "debug"); // "all", "debug", "error", "info", "trace"
Realm.App.Sync.setLogger(app, (level, message) => console.log(`[${level}] ${message}`));

const app = new Realm.App(appConfig);

// I've also tried to place it here instead
// Realm.App.Sync.setLogLevel(app, "debug"); // "all", "debug", "error", "info", "trace"
// Realm.App.Sync.setLogger(app, (level, message) => console.log(`[${level}] ${message}`));### Version

@mednche Thanks for creating this issue! The second example of setting the logger is the correct way. What version of Realm are you using?

I'm using [email protected]. When I use the second example of setting the logger, I get "Error: Exception in HostFunction: Cannot set the logger factory after creating the sync client". Any idea what tends to cause this error?

@mednche Sorry for the late reply.

It sounds like you are setting the logger after opening the Realm. It is not supported - you see to set the logger and loglevel before opening any Realm.
