Why Amplify DataStore is not starting?

I faced the problem with using DataStore and GraphQL in my react native app. When I'm trying to write/get any data I see this in the console:

LOG  [DEBUG] 56:36.775 DataStore - Starting DataStore
LOG  [DEBUG] 56:36.776 DataStore - Starting Storage

And then nothing happens. For example, in this code the second console log will not be executed:

console.log('Start');
const users = await DataStore.query(User);
console.log('End');

It's a fresh RN app and Amplify packages. I've tried to re-create the project from scratch and it didn't help.

  • There was a problem with Hermes, the polyfill from this issue helped to solve the problem: https://github.com/aws-amplify/amplify-js/issues/8176
