React native throws an error cannot read property 'render' of undefined?

Question

React

Good evening. When releasing a react native application, an error typeError: cannot read property 'render' of undefined. In dev everything works as it should.
What could be the problem?
I suspect the problem is with the shoutem/theme library. With connectStyle
ANSWER:
Found an error. The error was related to the shoutem/theme library, which appeared in the release version of the react native 0.50+ application
