ApolloClient onError doesn't catch mutation errors anymore

Here is my client configuration using Apollo Boost :

new ApolloClient({
  uri: `${window.location.origin}/api`,
  cache: new InMemoryCache(),
  onError({ graphQLErrors, networkError }) {
    if(graphQLErrors)
      graphQLErrors.forEach(error => notification.error({
        message: 'Error',
        description: error.message
      }))
    if(networkError)
      notification.error({
        message: 'Network Error',
        description: `A network error has occurred. Please check out your connection.`
      })
  },
  request(operation) {
    const currentUser = readStore('currentUser')
    currentUser && operation.setContext({
      headers: { authorization: currentUser.token }
    })
  }
})

Intended outcome: Before the bug, the onError callback used to catch errors just fine.

Actual outcome: Errors are said to remain uncaught and cause apps (using CRA in my case) to crash.

How to reproduce the issue: Try switching to the latest version of apollo-boost and just throw a Graphql error on the server.

Versions React : 16.12.0 Apollo-boost : 0.4.7

Any update on this? I have a pretty large app that relied on this pattern to minimize the amount of try/catch and .catch that was needed. Made for a super clean code base knowing I could rely on apollo-link-error when needed.

Not sure what changed, guess I need to look at my past few commits, but lately all mutation errors throw an unhandled error.

Is this change documented in a change log somewhere?
