1-4 - Empty Address

Possible Causes

1. The 1-4 error in registry.integration.RegistryDirectory is caused by invokerUrls being empty during the refreshInvoker process, which can be ignored.
2. The 1-4 error in registry.support.CacheableFailbackRegistry may be caused by a mismatch between the consumer and provider, and the “empty protection” being disabled.

Troubleshooting and Resolution Steps

1. Ensure that the service group configurations on both the Provider and Consumer sides correspond.
2. Ensure that the service version configurations on both the Provider and Consumer sides correspond.
3. Check whether enable-empty-protection in the registry center is set to true (default is true).
