I get the Failed building JavaScript bundle error. Here is the full error:

> While trying to resolve module `lottie-react-native` from file `C:\Users\zacha\addhoc\app\screens\UploadScreen.js`, the package `C:\Users\zacha\addhoc\node_modules\lottie-react-native\package.json` was successfully found. However, this package itself specifies a `main` module field that could not be resolved (`C:\Users\zacha\addhoc\node_modules\lottie-react-native\lib\index.js`. Indeed, none of these files exist:
