TypeError Could not create `Blob`, expected `Blob`, `dict` or an `Image` type(`PIL.Image.Image` or `IPython.display.Image`)

Description of the bug:

Getting this error sometimes. What does it mean? If I rerun the script, it is not raised every time, but only sometimes.

REQUEST_TIMEOUT = 90

# model is `gemini-1.5-flash`    
client = genai.GenerativeModel(model, system_instruction=system_instruction)

google_completion = await asyncio.wait_for(
    client.generate_content_async(
        messages,
        safety_settings={
            HarmCategory.HARM_CATEGORY_HARASSMENT: HarmBlockThreshold.BLOCK_NONE,
            HarmCategory.HARM_CATEGORY_HATE_SPEECH: HarmBlockThreshold.BLOCK_NONE,
            HarmCategory.HARM_CATEGORY_SEXUALLY_EXPLICIT: HarmBlockThreshold.BLOCK_NONE,
            HarmCategory.HARM_CATEGORY_DANGEROUS_CONTENT: HarmBlockThreshold.BLOCK_NONE,
        },
    ),
    REQUEST_TIMEOUT,
)

Actual vs expected behavior:

Actual:

TypeError Could not create `Blob`, expected `Blob`, `dict` or an `Image` type(`PIL.Image.Image` or `IPython.display.Image`).
Got a: <class 'NoneType'>
Value: None

Expected there to be no error

Right, that's not the best error.

This is at the step where it's trying to convert your input into the classes the api actually uses.

And you have a None in your list of contents or one of their lists of parts.

I should make these errors clearer. You need to track down where that None is coming from.
