I attempted to create a custom agent for a chat model, and this agent interacted with the custom agent, which in turn accessed either OpenAI's or Deepseek's chat model indirectly. The data formats returned from both the custom proxy and direct access to the chat model appear normal, but the content field is consistently empty. Below is the data returned by our access interface /v1/chat/completions:

This is the primary logic for our proxy service implementation, designed to receive a response from Deepseek and relay it directly to the aiagent.
// Forwarding to Deepseek
func forwardToDeepseek(w http.ResponseWriter, req APIRequest) {
body, err := json.Marshal(req)
if err != nil {
sendError(w, http.StatusInternalServerError, "Failed to marshal request")
return
}
httpReq, _ := http.NewRequest("POST", "https://api.deepseek.com/v1/chat/completions", bytes.NewReader(body))
httpReq.Header.Set("Authorization", "Bearer "+"sk-12312312dassdw123123")
httpReq.Header.Set("Content-Type", "application/json")
httpReq.Header.Set("Accept", "application/json")
client := &http.Client{Timeout: 30 * time.Second}
resp, err := client.Do(httpReq)
if err != nil {
sendError(w, http.StatusBadGateway, "OpenAI service error")
return
}
defer resp.Body.Close()
t, _ := ioutil.ReadAll(resp.Body)
// Returning the string
fmt.Fprintf(w, string(t))
}

I'm experiencing the same.
Do you have a contract?
