Root Cause

The gRPC request does not include the required authentication metadata (e.g., an authorization token) or the token is invalid.

generic

中文

gRPC 请求未包含所需的身份验证元数据（例如授权令牌），或者令牌无效。

Workarounds

  1. 95% success 
    md := metadata.Pairs("authorization", "Bearer "+token); ctx := metadata.NewOutgoingContext(context.Background(), md); resp, err := client.Call(ctx, ...)
  2. 85% success 
    Implement a token provider that obtains and caches valid tokens.

Dead Ends

Common approaches that don't work:

  1. 80% fail

    This weakens security and is not advisable in production.

  2. 90% fail

    The server will still reject it.
