seata 1.4 nacos配置的dataid sevice.vgroup-mapping已经变成service.vgroupMapping

default String getServiceGroup(String key) {
key = "service.vgroupMapping." + key;
if (!SERVICE_GROUP_NAME.contains(key)) {
ConfigurationCache.addConfigListener(key, new ConfigurationChangeListener[0]);
SERVICE_GROUP_NAME.add(key);
}

return ConfigurationFactory.getInstance().getConfig(key);
}

Start by locating the getServiceGroup method shown in the issue and inspect how ConfigurationFactory resolves the Nacos data ID. Compare the service.vgroup-mapping and service.vgroupMapping names against the Seata 1.4 configuration; done means the sample uses the current key and the configuration lookup works.
