Spring-ai Qianfan's chatmode returns an error issue due to the presence of system messages in the prompt.

Use the following code to execute correctly。

org.springframework.ai.qianfan.QianFanChatModel

public ChatCompletionRequest createRequest(Prompt prompt, boolean stream) { var chatCompletionMessages = prompt.getInstructions() .stream() .map(m -> new ChatCompletionMessage(m.getContent(), ChatCompletionMessage.Role.valueOf(m.getMessageType().name()))) .toList(); var systemMessageList = chatCompletionMessages.stream().filter(msg -> msg.role() == Role.SYSTEM).toList(); var chatMessages = chatCompletionMessages.stream().filter(msg -> msg.role() != Role.SYSTEM).toList();

......

var request = new ChatCompletionRequest(chatMessages, systemMessage, stream);

....
