Upgrade (or Relax) mongodb Dependency Version in @langchain/community to Align with Latest Requirements

Checked other resources

[X] I added a very descriptive title to this issue.
[X] I searched the LangChain.js documentation with the integrated search.
[X] I used the GitHub search to find a similar question and didn't find it.
[X] I am sure that this is a bug in LangChain.js rather than my code.
[X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

Steps to Reproduce:

Set up a project with mongodb@^6.7.0 as a dependency.
Add @langchain/community@^0.2.28 as a dependency.
Run npm install.
Observe the dependency conflict error.

Description

We are encountering a dependency conflict in our project due to a mismatch in the mongodb version required by the @langchain/community package. Our project requires mongodb@^6.7.0, but the @langchain/community package specifies a peer dependency on mongodb@^5.9.2. This mismatch leads to npm installation errors, preventing us from setting up our project.

Proposed Solution:

Upgrade the mongodb dependency in the @langchain/community package to align with the latest version required by other packages (i.e., mongodb@^6.7.0). This will resolve the dependency conflict and allow for smooth project setup.

Impact:

This issue blocks our project setup and development, requiring us to use workarounds like --legacy-peer-deps, which could lead to further issues down the line.
