ChatCompletionMessage$Role Serialization Failure When role is ""
Bug description JONS
{"id":"d7ae7c4a-1524-4fe5-9d58-e4d59b89d8f0","object":"chat.completion.chunk","created":1709899323,"model":"step-1-8k","choices":[{"index":0,"delta":{"role":"","content":"跃"},"finish_reason":""}],"usage":{"prompt_tokens":83,"completion_tokens":5,"total_tokens":88}}
Steps to reproduce role is “”
Error Code: ModelOptionsUtils$mapToClass
public static <T> T mapToClass(Map<String, Object> source, Class<T> clazz) {
try {
String json = OBJECT_MAPPER.writeValueAsString(source);
return OBJECT_MAPPER.readValue(json, clazz);
} catch (JsonProcessingException var3) {
JsonProcessingException e = var3;
throw new RuntimeException(e);
}
}
**Solution **
Set at program startup
ModelOptionsUtils.OBJECT_MAPPER.configure(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT, true);
Hi @chansanya , Could you confirm which ChatModel API are you using with this? In general, Spring AI relies on the chat response message role to process the response correctly. More information can be helpful to understand when the role can be empty. Thanks
I am using step-1-8k，the sample api document is https://platform.stepfun.com/docs/api-reference/chat/streaming.
I got a similar problem.
chat model: deepseek-chat reusing the OPEN API client
Enable com.fasterxml.jackson.databind.DeserializationFeature#FAIL_ON_NUMBERS_FOR_ENUMS may fix it,
but the OBJECT_MAPPER in org.springframework.ai.model.ModelOptionsUtils could not be customized.
my error logs：

I just override the class org.springframework.ai.model.ModelOptionsUtils in my project and customize the OBJECT_MAPPER.
I got a similar problem. chat model: deepseek-chat reusing the OPEN API client Enable
com.fasterxml.jackson.databind.DeserializationFeature#FAIL_ON_NUMBERS_FOR_ENUMSmay fix it, but theOBJECT_MAPPERinorg.springframework.ai.model.ModelOptionsUtilscould not be customized. my error

I just override the class
org.springframework.ai.model.ModelOptionsUtilsin my project and customize theOBJECT_MAPPER.
谢你的帮助和详细解答！这对我非常有帮助！
@PostConstruct
public void simpleModule() {
ModelOptionsUtils.OBJECT_MAPPER.configure(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT, true);
}
Ok, thanks for that, we will update the objectmapper to allow for this.
The definition of ObjectMapper is now,
public static final ObjectMapper OBJECT_MAPPER = JsonMapper.builder()
.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES)
.disable(SerializationFeature.FAIL_ON_EMPTY_BEANS)
.addModules(JacksonUtils.instantiateAvailableModules())
.build()
.configure(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT, true);
I added a utility method as well to pass in your own object mapper.
note we will have a deepseek module as deepseek is differentiating from openai api.
