title: React Native - Undefined is not an object (evaluating "iter[Symbol.iterator]")
body: <p>We just sent me a big react native project that I can't open and I can't figure it out why.
  I've got the message : &quot;Undefined is not an object (evaluating &quot;Iter[Symbol.iterator]&quot;)&quot;.
  I can't access the app because of it and didn't find any topic that helped me.</p>
  <p>Here the package.json :</p>
