hi @hanifmhd ,

I am sorry you are having troubles but I can not reproduce this problem with fresh react-native project.

Have you followed migration guide for version 3 ? I would also recommend going over the quickstart guide in order to make sure your integration is correct. Given available information I would speculate you are missing setBuildConfig in your MainApplication.java.

If the error still exists I would ask you to share a demo project which demostrates this problem.

thanks.

hi @maxkomarychev ,

Thank you so much for your guidance, i just read the changelog and there is additional configuration for v3 above. I missed the quickstart guide about setBuildConfig.

Right now, it's working well on Android and iOS, appreciate your help. Thank you.
