at java.base/java.lang.reflect.Method.invoke(Method.java:566)我想使用akhq GUI注册新模式，但我得到了错误主题未找到。我不明白这个错误。当我想创建新模式时，为什么主题应该存在？
更新
我试着用curl创建它：
curl -X POST -H“内容类型：application/vnd.schemaregistry.v1+json”-k --data @key http://my-custom-schemaregistry.org/subjects/MY_TOPIC-value/versions?normalize=false
它返回schema ID 123，但当我尝试GET时：
http://my-custom-schemaregistry.org/schemas/ids/123
我得到了：
{"error_code":40403,"message":"Schema 123 not found"}更新2
在日志中，我可以看到新模式：

为什么要在创建新模式时存在主题
因为你发布了一个 * 新版本 * 到一个主题，即使这是第一个版本。
您可以从
"GET /subjects/MY_TOPIC-key/versions/latest HTTP/1.1" 404中看到，它必须首先查找最新版本，然后才能注册，以便注册表执行向后兼容性检查对于第一个注册的版本，您应该忽略这些日志。您无法在服务器上禁用它们。
