Fix:
From:
llama_index_client/types/metadata_filter.py

class MetadataFilter(pydantic.BaseModel):
    """
    Comprehensive metadata filter for vector stores to support more operators.

To:
llama_index_client/types/metadata_filter.py

class MetadataFilter(pydantic.BaseModel):
    r"""
    Comprehensive metadata filter for vector stores to support more operators.

To resolve the SyntaxWarning: invalid escape sequence '\*' in the metadata_filter.py file, you can change the docstring to a raw string by prefixing it with r. This prevents Python from interpreting backslashes as escape characters.

Here's the fix:

From:

class MetadataFilter(pydantic.BaseModel):
    """
    Comprehensive metadata filter for vector stores to support more operators.
    """

To:

class MetadataFilter(pydantic.BaseModel):
    r"""
    Comprehensive metadata filter for vector stores to support more operators.
    """

This change will prevent the invalid escape sequence warning.

Hello, has this issue been solved?

I'm getting the same warning, and this is affecting a part of my app. I'm not able to visit some endpoints of my API. The feedback I'm getting is:

TypeError at /api/docs/
startswith first arg must be str or a tuple of str, not NoneType

...but this, I believe, is because of this warning I get when my app is running in production:

/python/lib/python3.12/site-packages/llama_cloud/types/metadata_filter.py:20: SyntaxWarning: invalid escape sequence '\*'

I already tried removing the llama_cloud package since my app didn't really use it (or so I thought) but I noticed that llamaindex wasn't running without the llama_cloud package so had to reinstall it

Surprisingly, everything works in my local environment and I'm able to access all endpoints. The error doesn't even show locally but once I deploy to production, I get the SyntaxWarning and the endpoints begin showing the TypeError

Any help?
