Failed to compile

Hi everyone

I get this error when Im typing heroku open on terminal.

Failed to compile

./src/index.js
Module build failed: ReferenceError: Unknown plugin "react-relay" specified in "/app/package.json" at 0, attempted to resolve relative to "/app"
at Array.map ()

This error occurred during the build time and cannot be dismissed.

Does anyone know how to resolve this?
