Hi everyone. I'm new to mobile development in general, and I'm trying to setup a project using Krell following this guide https://github.com/vouch-opensource/krell/wiki/Reagent-Tutorial. I got the AwesomeProject running with metro + emulator and started following the steps from the Krell guide. However, when I run npx react-native run-android I get the following error:

A problem occurred configuring project ':react-native-tcp-socket'.
> com.android.builder.errors.EvalIssueException: compileSdkVersion is not specified. Please add
 it to build.gradle

Nevermind. The problem was related with the react-native-tcp-socket. Updating it to the latest version in package.json solved my issue.
