Conflict with pymongo and bson packages in MongoDB VectorStore Component

[joaoguilhermeS]

Bug Description

There is a problem when trying to run the MongoDB Vectorstore component, it trows an exception of: "Please install pymongo to use MongoDB Atlas Vector Store" . But the actual problem is "ImportError: cannot import name '_get_object_size' from 'bson' (/home/joao/YAITEC/langflow/langflow-3-12/env/lib/python3.12/site-packages/bson/init.py)", so my guess is that there is a conflict between the internal bson of pymongo and the bson package itself set in the poetry environment.

Checking the code I think this might be related with #3607

Reproduction

1. Get a simple RAG template
2. Place the MongoDB Vectorstore as the Vectorstore
3. Set some configuration parameters (connection string, etc)
4. Run the Flow and check the error

Expected behavior

The Data should be ingested in the MongoDB Atlas environment as new documents in the choose collection.
Here is an example that I did with Langflow some time ago: .

Thanks @joaoguilhermeS for the catch, you are correct on all counts. PR has been created, will merge and get this in the next release.

A nightly build exists as well, which should pick up the change once merged - https://pypi.org/project/langflow-nightly/.

nice, my work around now is to down grade pymongo from 4.9.1 to 4.8.0

Still having the error on my side. Do I need to do something on Langflow?
