Bugsnag: The metadata recorded for key 'app' is not formatted as key/value pairs. Discarding.

For some reason the metadata stopped getting attached.

bugsnag-react-native/cocoa/BugsnagReactNative.m

Line 163 in cb360fd

if (![metadata[sectionKey] isKindOfClass:[NSDictionary class]]) {

I've tried this way:

bugsnagConfig.registerBeforeSendCallback((report) => {
        const metadata = report.metadata || {};
        metadata.clients = {
             clientName: 'foo'
        };
        report.metadata = metadata;
      });

and that way:

bugsnagConfig.registerBeforeSendCallback((report) => {
        report.addMetadata('state', 'device', 'test')
      });

I get both:
Bugsnag: The metadata recorded for key 'app' is not formatted as key/value pairs. Discarding.
and
Bugsnag: The metadata recorded for key 'clients' is not formatted as key/value pairs. Discarding.

in both cases.

What's going on? That same code used to work a while ago.

Thanks for the report, @SudoPlz. Which versions of react native and bugsnag-react-native are you using? I'll reproduce.

Follow up: I tried changing that NSLog to:

NSLog(@"Bugsnag: The metadata recorded for key '%@' is not formatted as key/value pairs for data %@ which is of type %@. Discarding.", sectionKey, metadata[sectionKey],NSStringFromClass( [metadata[sectionKey] class]));

and I now receive:
Bugsnag: The metadata recorded for key 'app' is not formatted as key/value pairs for data [object Object] which is of type __NSCFString. Discarding.

@kattrali I'm using:
react-native: 0.46.3
bugsnag-react-native: 2.3.1

Thanks!
