Root Cause

The authenticated user lacks the required role or permissions for the requested RPC, as enforced by server-side authorization logic.

generic

中文

经过身份验证的用户缺少请求RPC所需的角色或权限，由服务器端授权逻辑强制执行。

Workarounds

  1. 90% success Request elevated permissions from the admin and use a new token. 
    token := getAdminToken() // obtain token with required role
md := metadata.Pairs("authorization", "Bearer "+token)
ctx := metadata.NewOutgoingContext(context.Background(), md)
  2. 85% success Use a service account with necessary roles if available. 
    // Configure gRPC with service account credentials
conn, _ := grpc.Dial(target, grpc.WithPerRPCCredentials(oauth.NewServiceAccountTokenSource("path/to/key.json", "scope")))

Dead Ends

Common approaches that don't work:

  1. Re-authenticating with the same credentials. 100% fail

    Same user, same permissions; still denied.

  2. Using a different RPC with the same user. 80% fail

    Permission issue is user-specific, not method-specific.
