Describe the bug
I am trying to migrate my 0.78.0 react native application to 0.79.6 . I cannot run the app with aws-amplify library metro bundler is throwing an error.
Error is
TypeError: Cannot read property '__extends' of undefined, js engine: hermes
Cannot read property '__awaiter' of undefined
Seems like the library is incompatible with 0.79.6 hermes engine
Expected behavior
Should not throw any error when using library methods
Reproduction steps
Install the react native version 0.79.5
install the aws-amplify npm package
Use any of its Authentication methods
- Eg ```
Auth.signIn({
username,
password,
});
