Call DataChatServiceClient with Conversation leads to --> Suppressed: java.lang.RuntimeException: Asynchronous task failed at com.google.api.gax.rpc.ServerStreamIterator.hasNext(ServerStreamIterator.java:105)

Comece reproduzindo a falha com uma conversationId e compare-a com a solicitação funcional sem uma. Leia DataChatService.chat e forEachChatMessage e, em seguida, inspecione buildChatRequest e a construção de ConversationReference/DataAgentContext. Está concluído quando o chat baseado em conversa funciona sem o erro INTERNAL e o caminho sem conversa continua funcionando.

When calling the DataChatServiceClient with a conversation i got:

Here my Implementation:

 private ChatRequest buildChatRequest(String question, String conversationId) {
        String parent = locationName();

        Message userMessage = Message.newBuilder()
                .setUserMessage(UserMessage.newBuilder().setText(question).build())
                .build();

        ChatRequest.Builder requestBuilder = ChatRequest.newBuilder()
                .setParent(parent)
                .addMessages(userMessage);

        if (conversationId != null && !conversationId.isBlank()) {
            String conversationName = conversationName(conversationId);
            ConversationReference conversationReference = ConversationReference.newBuilder()
                    .setConversation(conversationName)
                    .setDataAgentContext(DataAgentContext.newBuilder()
                            .setDataAgent(configuredDataAgentName())
                            .build())
                    .build();
            requestBuilder.setConversationReference(conversationReference);
        } else {
            requestBuilder.setDataAgentContext(DataAgentContext.newBuilder()
                    .setDataAgent(configuredDataAgentName())
                    .build());
        }

        return requestBuilder.build();
    }

When calling without conversationId everything is working as expected.
