Amplify-js: S3 is not a constructor & Observable is not a constructor ERRORS

[orcunorcun]

Problem:

I was using Storage and subscription well on React Native, but now it doesn't work with same codes. It rejects with

_S3 is not a constructor_

for Storage,

_Observable is not a constructor_

for Subscription (Queries and mutations working well.)

Packages:

  "react": "16.9.0",
  "react-native": "0.61.2",
  "amazon-cognito-identity-js": "3.1.3",
  "aws-amplify": "1.2.3",
  "aws-amplify-react-native": "2.2.3",

Codes:

import awsconfig from './aws-exports';
import Amplify, {Storage} from 'aws-amplify';

Amplify.configure(awsconfig);

export const ImageDownloader = fileName => {
  return Storage.get(fileName, {track: true});
};

Same error for me "Object is not a constructor (evaluating 'new S3')"

[rarira]

same error @aws-amplify/storage.. v1.2.2 is fine.

@orcunorcun @Nitheesh-u @rarira I pushed a quick fix for that which is now published to unstable, can you please test it with this version(unstable tag) and let us know if that solved this issue?

[itsgitz]

@Amplifiyer well, I've changed the version with unstable tag:
"aws-amplify": "^1.2.3-unstable.0"

And then new warning has occured:
[Unhandled promise rejection: Error: No credentials, applicationId or region]

So, I disable Analytics like this:
Amplify.configure({ Analytics: { disabled: true } })

And it works for both S3 and Subscriptions after changed to unstable version, thanks!

Edit:
No Auth module registered in Amplify has appeared when I'm trying to publish MQTT message using PubSub from aws-amplify

[adamsythe]

why is this closed?

[itsgitz]

@adamsythe I don't know why, but I'm still waiting for update. My application can't subscribe using aws-amplify with unstable version

[Amplifiyer]

@itsgitz @adamsythe, can you please post your error messages and code samples here that is causing the issue? Please also verify the unstable version of aws-amplify packages you are consuming in the node_modules folder.

[itsgitz]

@Amplifiyer for now, there's no problem with S3 but I got this error/warning messages while publishing, the message using MQTT:

And this is my sample codes:

import { PubSub } from 'aws-amplify'

PubSub.publish(topic, {
    command: 'open',
});

I'm using "aws-amplify": "^1.2.4-unstable.5".

Thank you :)

[adamsythe]

^1.2.4-unstable.5 seems to be working from me but surely this should stay live at least until the fix goes into an official release?

[Amplifiyer]

The fix has reached into a stable release. @adamsythe, github automatically closes the issue when tagged with fixes directive, and our master commits go to unstable release (automatically) but not to stable releases

[itsgitz]

@Amplifiyer thanks! It solved with latest stable version "aws-amplify": "^1.2.4"

Resolving as the release was completed yesterday as @Amplifiyer called out. Please feel free to reopen if you are still experiencing this issue.
