Note: This answer (and arguably the whole question) is now outdated, since mutation errors show up in catch in more recent versions of Apollo Client.

GraphQL errors from the mutation currently show up in the errors field on the response inside then. I think there's definitely a claim to be made that they should show up in the catch instead, but here's a snippet of a mutation from GitHunt:

// The container
const withData = graphql(SUBMIT_REPOSITORY_MUTATION, {
  props: ({ mutate }) => ({
    submit: repoFullName => mutate({
      variables: { repoFullName },
    }),
  }),
});

// Where it's called
return submit(repoFullName).then((res) => {
  if (!res.errors) {
    browserHistory.push('/feed/new');
  } else {
    this.setState({ errors: res.errors });
  }
});
