                 buildConfigField "String", "ENVFILE", "\".env.development\""
             }
             production {

             }

         }

    }
}

project.ext.envConfigFiles = [
    developmentDebug: ".env.development",
    developmentRelease: ".env.development",
    productionDebug: ".env.production",

]

project.ext.react = [

Hello @mrenann thank you for reaching out! I see you are using new arch you could try this workaround https://github.com/microsoft/react-native-code-push/issues/2083#issuecomment-1411745157 and see if it works for you. If not i suggest not use new arch as we don't support it, i belive you can still opt out from it.

[mrenann]

Hello :) Thanks for the help I looked, but I didn't quite understand where I should put it, I'll try to send a message there to understand

[DordeDimitrijev]

I understand, but you can always disable new arch since as i said this is a workaround and we don't plan on supporting new arch for react-native-code-push.
