Spring AI com.fasterxml.jackson.databind.JsonMappingException: Unexpected end-of-input: was expecting closing quote for a string value at [Source: REDACTED (StreamReadFeature.INCLUDE_SOURCE_IN_LOCATION disabled); line: 43, column: 43]

调用gpt4.1报错，大模型输出的结果被截断导致反序列化失败，怀疑是completionTokens超过了1024，但我并没有显式设置token任何长度限制的参数。

是spring ai本身对模型输出长度做了限制吗？请问怎么解决？

Here is the English translation:

Calling GPT-4.1 results in an error. The output from the large model is being truncated, causing deserialization to fail. I suspect that the completionTokens exceeded 1024, but I did not explicitly set any token length limit parameters.

Does Spring AI itself impose a limit on the output length of the model? How can I resolve this issue?
