MongoDBAtlasDocumentStore errors on : "invalid parameter: expected an object (filter)"

[Pash10g]

Describe the bug
When running the following demo collab according to Haystack docs :

https://github.com/mongodb-developer/GenAI-Showcase/blob/main/notebooks/rag/Haystack_MongoDB_Atlas_RAG.ipynb

To Reproduce
Steps to reproduce the behavior:

https://github.com/mongodb-developer/GenAI-Showcase/blob/main/notebooks/rag/Haystack_MongoDB_Atlas_RAG.ipynb

I get the following error in the last code block:

OperationFailure: invalid parameter: expected an object (filter), full error: {'ok': 0.0, 'errmsg': 'invalid parameter: expected an object (filter)', 'code': 10065, 'codeName': 'Location10065', '$clusterTime': {'clusterTime': Timestamp(1716804481, 2), 'signature': {'hash': b'\xd0\xf5\xce`6]j\xb5\xbf\xf2CN\x03\x9a3\xb2HiC\x9c', 'keyId': 7317623845651742726}}, 'operationTime': Timestamp(1716804481, 2)}



The above exception was the direct cause of the following exception:

DocumentStoreError                        Traceback (most recent call last)

DocumentStoreError: Retrieval of documents from MongoDB Atlas failed: invalid parameter: expected an object (filter), full error: {'ok': 0.0, 'errmsg': 'invalid parameter: expected an object (filter)', 'code': 10065, 'codeName': 'Location10065', '$clusterTime': {'clusterTime': Timestamp(1716804481, 2), 'signature': {'hash': b'\xd0\xf5\xce`6]j\xb5\xbf\xf2CN\x03\x9a3\xb2HiC\x9c', 'keyId': 7317623845651742726}}, 'operationTime': Timestamp(1716804481, 2)}

I believe its an issue with the fact that now every time a "filters" element is being passed even if its none and the server does not expect that.

Describe your environment (please complete the following information):

• OS: Google collab
• Haystack version: latest

Looks like the issue was solved in a latest release.
