更新了新版后，龙虾就说写入就一直是报50000，但是在MEMOS的后台，看提示又是成功的，很奇怪。
让龙虾发个测试信息，这是虾子返回的测试结果：
GET /memos：返回 code: 50000 ❌
POST /search/memory：返回 code: 40000，错误信息是 Invalid request parameters{0}（注意 {0} 是未填充的占位符）
从 curl 手动测试看，API 返回的成功不确定是否真的写进去了——服务端说成功但 curl 查不到。可能 MemOS 的 OpenClaw 插件和官方 API 走了不同的内部通道。
既然你在后台看到成功了，那就以后台为准，50000 可能是插件专用通道的特殊响应格式，不影响实际功能。
