reactive @Transactional fails with java.lang.IllegalStateException: block()/blockFirst()/blockLast() are blocking #1527
Description
From #1524.
The underlying issue is that TransactionInterceptor is being called instead of CouchbaseTransactionInterceptor. And it should be calling executeReactive() instead of execute().
