OpenAI-Compatible API agent completion

[Hekas1]

I do this request example this query with my data
curl --request POST
--url http://{address}/api/v1/agents_openai/{agent_id}/chat/completions
--header 'Content-Type: application/json'
--header 'Authorization: Bearer <YOUR_API_KEY>'
--data '{
"model": "model",
"messages": [{"role": "user", "content": "Say this is a test!"}],
"stream": true
}'

And here is the result that I receive

2025-08-02 23:37:35.492 | 2025-08-03 03:37:35,491 INFO 31 task_executor_e36c011ab7ff_0 reported heartbeat: {"name": "task_executor_e36c011ab7ff_0", "now": "2025-08-03T03:37:35.491+08:00", "boot_at": "2025-08-02T20:19:50.084+08:00", "pending": 0, "lag": 0, "done": 0, "failed": 0, "current": {}}

For clarity, I will use the simplest version:
Begin - agent - message

Chat embed works

OpenAI compatible stopped working after updating to version 0.20.0.
Also, the question is, did I understand correctly that all agents need to be rebuilt, since the new logic is different and needs to be created anew.

But if I call the agent via API_openAI
using this
http://{address}/api/v1/agents_openai/{agent_id}/chat/completions
then I get an error

Please help

My searches have not been successful. Are there any special requirements for setting up agents, for compatibility with the openai calling scheme
