Connection failed: Buffer is not defined - Error when subscribing to AWS Amplify (graphql) Subscriptions after update to v4.7.0

I have just updated from Amplify-cli 4.0.0 to 4.7.0 and now I am getting these errors when attempting to listen for my subscriptions.

{provider: AWSAppSyncRealTimeProvider, error: {…}}
provider: AWSAppSyncRealTimeProvider {_config: {…}, socketStatus: 0, keepAliveTimeout: 300000, subscriptionObserverMap: Map(0), promiseArray: Array(0), …}
error:
errors: Array(1)
0:
message: "Connection failed: Buffer is not defined"
__proto__: Object
length: 1
__proto__: Array(0)
__proto__: Object
__proto__: Object

I am using Ionic 4, and just before the update everything was working just fine.
