Rollbacks using liquibase Api not being made - liquibase

Question

I am trying to do a rollback using Liquibase api but for some reason the rollbacks aren't being made
try {
Properties properties = PropertiesLoaderUtils.loadAllProperties("application.properties");
String dbUrl=properties.getProperty("spring.datasource.url");
String dbUsername=properties.getProperty("spring.datasource.username");
String dbPassword=properties.getProperty("spring.datasource.password");
String changelogPath=properties.getProperty("spring.liquibase.change-log");
Connection connection = openConnection(dbUrl,dbUsername,dbPassword);
Database database = DatabaseFactory.getInstance().findCorrectDatabaseImplementation(new JdbcConnection(connection));
Liquibase liquibase = new liquibase.Liquibase(changelogPath, new ClassLoaderResourceAccessor(), database);
liquibase.rollback(1,"");
} catch (SQLException | IOException | LiquibaseException e) {
logger.error(e.getMessage());
}
This is the message I am getting in the command line

Do you want to see this operation's report in Liquibase Hub, which improves team collaboration?
If so, enter your email. If not, enter [N] to no longer be prompted, or [S] to skip for now, but ask again next time (default "S"):
