No pubsub module applied for subscription.

yukitaka13-1110 commented 5 years ago

I encountered a problem as follows issue https://github.com/aws-amplify/amplify-js/issues/3484

And I tried to change aws-amplify import statement following this solution

I solved it but I got another error as follows

Error: No pubsub module applied for subscription

I don't use PubSub in .vue file. Perhaps, it was triggered by limiting import. What should I do ?

Hey @yukitaka13-1110,

Are you using the API category for graphql subscriptions? Also, can you post which versions of amplify modules you are using.

I have the same issue, with the api category it uses pubsub for subscriptions, but amplify doesn't generate any config for it?
