Thanks for reporting @EpariNigam, it looks like we're trying to initialize data binding for a .riv file that doesn't have it configured. We'll get this fixed.

For you to step around this in the meantime, you can set app:riveAutoBind="false" which is what you'd want to set it to if you're not making use of data binding.

[EpariNigam]

Understood. Thanks for the quick reply. With auto bind false, it is working fine.
