Earlier Accepted Answer. After talking with fabric team, they told me that it is a known issue. To solve this, we have to include the apply plugin: 'io.fabric' in the build.gradle file of the app module. Including this will give the following warning:

WARNING: API 'variant.getExternalNativeBuildTasks()' is obsolete and has been replaced with 'variant.getExternalNativeBuildProviders()'. It will be removed at the end of 2019.

You can ignore this warning for now. Hopefully a fix for this issue will be provided soon.

It is fixed in the latest version, you can update your version with 1.28.0.

buildscript {
  // ... repositories, etc. ...

   dependencies {
       // ...other dependencies ...
       classpath 'io.fabric.tools:gradle:1.28.0'
   }
}
