What causes the RuntimeError Event loop is closed in Django Rest Framework when working with Google Generative AI and how can I fix it

Question

Can you tell me What causes the RuntimeError('Event loop is closed') in Django Rest Framework when working with Google Generative AI, and how can I fix it?

Answer 1

The RuntimeError: Event loop is closed error in Django Rest Framework (DRF) when working with Google Generative AI occurs due to improper handling of asyncio event loops, especially in environments like Jupyter, ASGI, or when using async functions in synchronous views.

Here is the code snippet you can refer to:

In the above code we are using the following key points:

• Uses nest_asyncio.apply() to prevent event loop closure in nested async environments.
• Creates a new event loop with asyncio.new_event_loop() to ensure async functions execute correctly.
• Handles AI generation asynchronously with generate_content_async().
• Integrates with Django REST Framework using JsonResponse in a synchronous view.

Hence, fixing the RuntimeError: Event loop is closed in Django Rest Framework requires using nest_asyncio, properly managing async event loops, and ensuring async calls are executed in a new event loop when necessary.
