Call MODEL：AntangelMed ERR： *__checkpoint ⇢ 400 BAD_REQUEST from POST

[JasonLonglong]

I'm trying to call the antangelmed model in Spring AI, but I keep getting a BadRequest error. I've tried using Spring AI's simplest method, but it still gives the same error. Is it because the model isn't compatible yet, or does the model not support this method of invocation?

code：
Flux flux = chatClient
.prompt()
.user(req.getMessage())
.stream()
.chatResponse();
