Bundle Config is Missing

Hello,
i jsut installed the software and exported the example project ,
then uploaded to developers.facebook.com
and I got this error :

You must include a bundle config in your upload. To create a bundle config, please refer to: developers.facebook.com/docs/ga … dle-config.

If you’ve used the Facebook export, then it’s a bug, I think it’s the second time I’ve heard about this problem
