JSON schema for array of objects #15
Description
Hi, I'm trying out the API for something I'm building, and I'm having issues with json responses.
My code:
const completion = await client.chat.completions.create({
messages: [{ content: promptContent, role: 'user' }],
model: 'Llama-4-Scout-17B-16E-Instruct-FP8',
response_format: {
type: 'json_schema',
json_schema: {
name: 'similarity_scores',
schema: {
type: 'array',
items: {
type: 'object',
properties: {
productID: { type: 'string' },
similarity: { type: 'number', minimum: 0, maximum: 10 },
},
required: ['productID', 'similarity'],
additionalProperties: false,
},
},
},
},
});The api response:
BadRequestError: 400 {"title":"Bad request","detail":"Response format 'json_schema' is an invalid JSON schema object","status":400}

}
Let me know if the issue resides on my end, and a possible fix. I couldn't find any related information in the only docs I found related to json schema responses - they only mention how to manage objects.
