1 month ago It looks like after you created your own HttpMessageConverter, OpenAiApi failed to deserialize the JSON string to the correct type Embedding, but used JSONObject instead. It's hard to tell the root cause without reproducible code.
The usage of fastjson is caused by invocation of EmbeddingModel.dimensions() method to get the dimensions for observability reason.
[[问题描述 简要描述您碰到的问题。 class com.alibaba.fastjson2.JSONObject cannot be cast to class org.springframework.ai.openai.api.OpenAiApi$Embedding (com.alibaba.fastjson2.JSONObject and org.springframework.ai.openai.api.OpenAiApi$Embedding are in unnamed module of loader 'app')
环境信息 请填写以下信息：
OS信息： [e.g.：macos M1 max] JDK信息： [e.g.：Openjdk 21] 版本信息：[e.g.：Fastjson2 2.0.52 和2.0.51] 重现步骤 如何操作可以重现该问题： 使用spring ai 自动配置，在使用 spring ai 的 vectorStore.add(documents)时会报如题错误（此方法是个void），但是我并未进行行fastjson转换 image
//可在此输入示例代码 image 期待的正确结果 对您期望发生的结果进行清晰简洁的描述。
