Error processing chat completion #1005

Open whiteInJava opened 6 days ago

whiteInJava commented 6 days ago

When using the OpenAiChatClient of SpringAI to call the output stream method, the error message keeps getting: Error processing chat completion -- Java. lang. NullPointerException: null

Instead of streaming output, it is normal and I cannot solve this problem. How should I troubleshoot this issue? My environment is JDK17 SpringBoot3. x Here is the complete error message: java.lang.NullPointerException: null at java.base/java.util.Objects.requireNonNull(Objects.java:208) ~[na:na] at

I don't think implementation OpenAiChatClient exists. Do you mean OpenAiChatModel like the following?

https://github.com/spring-projects/spring-ai/blob/f171b0fa5e8612a793a4599ad57de7ff598cd68f/models/spring-ai-openai/src/test/java/org/springframework/ai/openai/chat/OpenAiChatModelWithChatResponseMetadataTests.java#L61

By the way, I strongly suggest using constructor injection instead of field injection to catch similar errors at compile-time instead of at runtime. If you hover over @Autowired, you'll get this refactoring recommendation.
