该代码已到达“填充要执行的迁移”日志。但是，没有AAA，EEE和CCC日志都可以访问，因此doOnSuccess内部没有任何代码正在运行。对于我如何解决此问题的任何帮助，将不胜感激。

databaseclient.execute().sql("CREATE TABLE IF NOT EXISTS " + TRACKING_TABLE +" ("+PROPERTY_SERVICE+ " varchar(255) NOT NULL," + PROPERTY_VERSION+" float(4) NOT NULL," +PROPERTY_SCRIPT+" varchar(255) NOT NULL);")
                .then()
                .concatWith(databaseclient.execute().sql("CREATE TABLE IF NOT EXISTS " + TRACKING_SEAL_TABLE+" ("+PROPERTY_SERVICE+ " varchar(255) NOT NULL,"+ PROPERTY_VERSION+" float(4) NOT NULL);")
                        .then())
                .doOnComplete(() -> {
                    log.info("Populating migrations to be executed");// reaches here
                    databaseclient.select().from(TRACKING_SEAL_TABLE).as(MigrationSealDetails.class).fetch().all()       .collectList()
                            .map()//mapping function
                            .doOnError(e -> log.log(Level.SEVERE,"EEE",e))
                            .doOnSuccess(highestSealPerService -> {
                                log.info("AAA");
                                databaseclient.select().from(TRACKING_TABLE).as(MigrationDetails.class).fetch().all()
                                        .collectList()
                                        .doOnSuccess(migrationsExecuted -> {
                                            // other code
                                        }).block();
                            }).block();
                }).blockLast();
        log.info("CCC");
