Has any one successfully used Spring AI with Perplexity Agent API?

Hello,
Has anyone used the Perplexity Agent API with Spring AI?
I am trying to add Perplexity support in embabel . Since /chat/completions/ does not support agent, I have to use v1/agent but then I use the Spring AI’s OpenAI api’s but I ran into the below error.

{

  "error": {

    "message": "validation failed: input array cannot be empty",

    "type": "invalid_request",

    "code": 400

  }

}

After debugging further, what I understood is, it is because of the request format used by Spring AI.
I can reproduce the same error using the curl if I use the same request format.
curl https://api.perplexity.ai/v1/agent \

-H “Authorization: Bearer $PERPLEXITY_API_KEY” \

-H “Content-Type: application/json” \

-d '{

"model": "perplexity/sonar",           

"messages": \[

  {"role": "system", "content": "Say OK"},

  {"role": "user", "content": "test"}

\],

"temperature": 0.6,

"max_tokens": 100

}’ | jq

For eg: if I change the URL to https://api.perplexity.ai/chat/completions and the model , it works fine. Therefore, the issue is the way currently Spring AI send the request to the Perplexity .

Before digging further into the Spring AI request model, I am wondering whether anyone has really successfully been able to use Spring AI to use the agent API?

Just changing the URL to https://api.perplexity.ai/v1/responses as mentioned in the doc OpenAI Compatibility - Perplexity also did not work.
