Exceptions on Anthropic and OpenAI integrations in the latest version

How do you use Sentry?

Sentry Saas (sentry.io)

Version

2.29.1

Steps to Reproduce

When you call:

from anthropic import AsyncAnthropicVertex, omit

client = AsyncAnthropicVertex()

client.messages.create(
                    max_tokens=max_answer_tokens,
                    system=prompt if user_input else omit,
                    messages=[
                        {
                            "role": "user",
                            "content": user_input if user_input else prompt,
                        }
                    ],
                    model=model,
                    tools=omit,
                    stream=True,
                )

You get an error: "object of type 'Omit' has no len()"

The error comes from here:
https://github.com/getsentry/sentry-python/blob/master/sentry_sdk/integrations/anthropic.py#L174-L179

Both Anthropic and OpenAI latest version defaults to Omit instead of NOT_GIVEN:

https://github.com/anthropics/anthropic-sdk-python/blob/main/src/anthropic/resources/messages/messages.py#L357-L380

We saw some similar errors in OpenAI that might be related: NotGiven has no len()

Expected Result

Both Anthropic and OpenAI shouldn't raise when we pass the argument as Omit

Actual Result

Anthropic and OpenAI are raising when we pass the argument as Omit

@jutogashi the open ai problem was fixed in
https://github.com/getsentry/sentry-python/releases/tag/2.42.1
