FIX: correctly initialize embedder for crew knowledge

[androw]

embedder_config doesn't exist in Knowledge and should be replaced with embedder as it's done in the agent.py file.

It's fixing part of #2033 and #2023.

Overview

This pull request addresses a critical issue regarding the parameter initialization within the create_crew_knowledge method in src/crewai/crew.py. It modifies the parameter name from embedder_config to embedder, ensuring that the correct argument is passed to the Knowledge class for proper initialization.

Changes Analyzed

• File: src/crewai/crew.py
• Parameter Change:
  • Old Code: embedder_config=self.embedder
  • New Code: embedder=self.embedder

This fix resolves a parameter mismatch that could lead to improper initialization of the knowledge management system.

Findings

1. Parameter Name Correction

The adjustment made is essential as it ensures the correct parameter is passed to the Knowledge class, thereby preventing potential functional issues within the system when initializing the crew's knowledge base.

2. Quality Assessment

• ✅ Bug Fix: Correctly addresses the parameter naming issue.
• ✅ Code Clarity: The updated code is straightforward and enhances readability.
• ⚠️ Documentation: The method would benefit from proper documentation regarding its parameters.
• ⚠️ Error Handling: Additional checks for the embedder parameter could prevent runtime errors and improve robustness.

Recommendations

1. Enhance Parameter Documentation

To further improve the maintainability of the code, I recommend updating the docstring of the create_crew_knowledge method and adding type hints for better clarity:

def create_crew_knowledge(self) -> "Crew":
    """
    Creates and initializes the crew's knowledge base.

    Returns:
        Crew: The current crew instance with initialized knowledge.
    """

2. Implement Error Handling

To safeguard against potential issues arising from uninitialized parameters, consider adding validation for the embedder parameter:

def create_crew_knowledge(self) -> "Crew":
    if (
        self.knowledge_sources
        and not self.knowledge
    ):
        if not self.embedder:
            raise ValueError("Embedder must be configured before creating crew knowledge")

        self.knowledge = Knowledge(
            sources=self.knowledge_sources,
            embedder=self.embedder,
            collection_name="crew",
        )

Conclusion

This PR effectively addresses an important parameter naming issue that is critical for the correct functioning of the system. While the proposed changes are valid, implementing the suggested improvements for error handling and parameter documentation would significantly enhance the overall quality of the code.

Verification Steps

1. Confirm that the Knowledge class correctly handles the embedder parameter.
2. Validate that the knowledge base initializes correctly with the updated parameter.
3. Testing various embedder configurations should ensure consistent and expected behavior.

The PR can be approved with the understanding that these suggested improvements will be entertained for better code maintainability and robustness.
