# 服务端会查用户是否存在（user RPC GetDesignateUsers）；若 SELF_USER_ID 未注册，
# 返回空列表后 rpcli.firstValue 会包装为 ErrRecordNotFound（errDlt: record not found）。
# 处理：先注册该用户，或 export SELF_USER_ID=已存在用户，或 export TOKEN=已有用户 token 跳过拉 token。
#
# HTTP 404 + 响应体 "404 page not found"（Gin）：当前连上的 API 进程路由表里没有该路径。
# 本仓库已注册 POST /group/get_common_groups_with_friend（见 internal/api/router.go）。
# 处理：用当前代码重新编译/替换镜像并重启 openim-api，或确认 API_BASE 指向的就是带该路由的实例（无错误路径前缀/反代截断）。
