OpenAiChatMessageIterator

Hello, @anaconda777
You need to import the correct class from the OpenAI provider module.
At the top of your file (modules/contrib/ai_provider_vllm/src/Plugin/AiProvider/VllmProvider.php),
Add:
use Drupal\ai_provider_openai\OpenAiChatMessageIterator;

Thank you!

Thanks, that worked.
