我正在尝试调用wso2api来在wso2identity服务器中创建新用户。wso2 api如下：使用java调用服务时，出现如下错误：

curl -v -k --user admin:admin --data "{"schemas":[],"name": { "familyName":"family_name","givenName":"given_name"},"userName":"user_name","password":"pass_word", "emails":[{"primary":true,"value":"im@example.net","type":"work"},{"primary":false,"value":"im2@gmail.com","type":"home"} ] }" --header "ContentType:application/json" https://localhost:9443/wso2/scim/Users

错误消息是：

我已经创建了一个keystore文件（client.keystore）并复制到src/main/resources/meta-inf/resources/文件夹中，但问题仍然存在。如果有人面临这个问题，请提出解决办法。
