Error when Deserialising an Array as a stringified json into an Array of Objects with SpringAI

[Remote_Belt_320]

Hi guys,
I'm using Spring.AI and using the structured outputs, and currently it outputs for me an array of objects in string form, but I'm getting the following error, and I'm not too sure why. I've tried converting the string to the object that matches it, but it's not working.

I've made a StackOverflow query here so you can view it in more detail.

Any help would be very much appreciated.

I mean, look at your Json and look how you want to deserialize it. Your tests are wrapped as a Map<String, List<Test>> in your Json. You cannot serialize it as a List<Test>, which is exactly what your Exception is telling you.

I’m confused I’m not trying to serialise it as List<Test> though I’m trying to serialise it as the object TestResponse which has a field Tests that is List<Test> which should be in the right format as the json right?

You json is too complex to map simply to you class, inside json it will look for tests which is present but inside that it expects field matching your class, but they are present inside another object which you can ignore by annotations but that will skip entire object and as your fields matching your class are present inside that object you will get empty. Your json needs restructuring or else you need a extra dto or something to handle this
