我使用以下代码成功创建了 EmbeddedAssistantStub。

EmbeddedAssistantGrpc.EmbeddedAssistantStub mAssistantService = EmbeddedAssistantGrpc.newStub(channel)
                                  .withCallCredentials(MoreCallCredentials.from(
                                            Credentials.fromResource(mClientId,mRefreshToken,mAccessToken)
                                   ));

在此之后，我将音频数据传递给 StreamObserver，当时发生了以下异常。
