JMeter加载客户端JKS密钥库报错No key(s) found的排查求助

大家好，我最近在尝试用JMeter对HTTPS服务器执行测试，配置了包含客户端证书的JKS密钥库，但运行时一直遇到报错，具体日志如下：

o.a.j.u.JsseSSLManager: SSL session context: per-thread

2022-04-07 17:22:54,741 INFO o.a.j.u.SSLManager: JmeterKeyStore Location: client.jks type JKS

2022-04-07 17:22:54,758 ERROR o.a.j.u.SSLManager: Problem loading keystore: No key(s) found

目前我已经做了这些排查：

• 确认密钥库是JKS类型，里面包含一个.cer格式的证书
• 已经在system.properties中配置了正确的密钥库路径和密码
• 通过命令确认证书确实存在于密钥库内

想请教一下，还有哪些可能的排查方向或者我可能忽略的点？
