Amplify-js: v1.0.2 Runtime error with @types/zen-observale: error TS2300: Duplicate identifier 'Subscriber'.

[XCarle]

Problem with npm dependencies.

I tried some npm dedupe which did not fix the problem.

I think the Subscriber is defined in rxjs.

I've got the same issue

Downgrading to 1.0.1 seemed to fix this issue for me. npm i -S [email protected]

Unable to run a server created with create-react-app due to this bug. This bug was also seen in ApolloGraphQL:

https://github.com/apollographql/apollo-link/pull/623

and there is an effort by @types/zen-observable to resolve it from within the zen-observable types library:

Thanks @XCarle. I ran into similar issues like below
_
node_modules\@aws-amplify\api\node_modules\@types\zen-observable\index.d.ts (32,14): error TS2300: Duplicate identifier 'Subscriber'.
node_modules\@aws-amplify\pubsub\node_modules\@types\zen-observable\index.d.ts (32,14): error TS2300: Duplicate identifier 'Subscriber'._

I tried npm dedupe that worked for me.
Before running npm dedupe, ran the npm find-dupes and found the below changes are being made

_remove @types/zen-observable 0.5.4 node_modules\@aws-amplify\pubsub\node_modules\@types\zen-observable
move @types/zen-observable 0.5.4 node_modules\@types\zen-observable node_modules\@aws-amplify\api\node_modules\@types\zen-observable_

@XCarle,

Are you still experiencing this issue?

[milesbeyond]

@jordanranz I am. I've tried __npm dedupe__ but to no avail. Any other ideas?

I had the issue at v1.1.19, and just updated to v1.1.22, but that did not include a fix.

[amaingot]

Is anything happening with this issue? Looks like it is still happening for me too. I'm on v1.1.23.

[elorzafe]

@cheeks @amaingot can you paste your package.json to try to reproduce the problem.

[alebiavati]

Closing issue as inactive, please open another issue with more details if you still need support.
