Did you try to use the correct tag for your RN version ?

v0.43-v0.44 | v2.0+ (RN refactored uimanager dependencies)

I had the same problem and then I downgrade RNCodePush to the V2.1.1 tag and everything is working fine.

What shall I do to make it work properly?

What should be the exact react-native and react-native-code-push version to use for stable build.

Hi there @iamhardik08 , that looks like your version of RN is not compatible with RNCP.
You should use RNCP v3.0.0+ this way.
Please checkout our compatibility table: https://github.com/Microsoft/react-native-code-push#supported-react-native-platforms
