How to set the responseFormat as JsonSchema without a dedicated record/class

[jflebeau]

Hi, let's say I have a Map<String, Object> or even just a String representing a valid Json schema, is there a way to construct the required ResponseFormat? I couldn't find it in the documentation / examples.

As a workaround, I did find a way to convert my JSON schema into a form compatible with the ResponseCreateParams.text() method. I was inspired by the example ResponsesStructuredOutputsRawExample.java.

Pseudocode:

JsonNode schemaJsonNode; // my JSON schema as Jackson JsonNode
ResponseFormatTextJsonSchemaConfig.Schema.Builder b =
            ResponseFormatTextJsonSchemaConfig.Schema.builder();
schemaJsonNode.fields().forEachRemaining(field -> 
    b.putAdditionalProperty(
        field.getKey(), 
        JsonValue.fromJsonNode(field.getValue()) // handles tree traversal internally
    )
);
ResponseTextConfig textConfig = ResponseTextConfig.builder().schema(b.build());
ResponseCreateParams.builder().text(textConfig);
...

YMMV but this approach is working for me.
