[BUG] Save method not working for Memories

[Dev-Khant]

Description

I was trying to use memory but found out that save function is not being called.

Steps to Reproduce

import os
from crewai import Agent, Task, Crew, Process

os.environ["OPENAI_API_KEY"] = "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"

# Define your agents
researcher = Agent(
    role="Researcher",
    goal="Conduct thorough research and analysis on AI and AI agents",
    backstory="You're an expert researcher, specialized in technology, software engineering, AI, and startups. You work as a freelancer and are currently researching for a new client.",
    allow_delegation=False,
    memory=True,
)

writer = Agent(
    role="Senior Writer",
    goal="Create compelling content about AI and AI agents",
    backstory="You're a senior writer, specialized in technology, software engineering, AI, and startups. You work as a freelancer and are currently writing content for a new client.",
    allow_delegation=False,
    memory=True,
)

# Define your task
task = Task(
    description="Generate a list of 5 interesting ideas for an article, then write one captivating paragraph for each idea that showcases the potential of a full article on this topic. Return the list of ideas with their paragraphs and your notes.",
    expected_output="5 bullet points, each with a paragraph and accompanying notes.",
)

# Define the manager agent
manager = Agent(
    role="Project Manager",
    goal="Efficiently manage the crew and ensure high-quality task completion",
    backstory="You're an experienced project manager, skilled in overseeing complex projects and guiding teams to success. Your role is to coordinate the efforts of the crew members, ensuring that each task is completed on time and to the highest standard.",
    allow_delegation=True,
    memory=True,
)

# Instantiate your crew with a custom manager
crew = Crew(
    agents=[researcher, writer],
    tasks=[task],
    manager_agent=manager,
    process=Process.hierarchical,
    memory=True,
)

# Start the crew's work
result = crew.kickoff()

Expected behavior

Here the save function of each memory i.e ShortTermMemory, LongTermMemory, EntityMemory should be called.

Screenshots/Code snippets

I tried printing every function of the memory class but it can be seen that no save call is being made. Only search is done and it empty results and nothing is being added.

Operating System

macOS Sonoma

Python Version

3.10

crewAI Version

0.51.1

crewAI Tools Version

0.8.3

Virtual Environment

Venv

Evidence

Possible Solution

Save function needs to be called properly.

Additional context

Nothing much

Please upgrade to latest version 0.70.1 and see if it still occurs as your versions are quite far behind now

Hey @theCyberTech I tried with latest version and I'm facing with chromadb now.

UniqueConstraintError: Collection short_term already exists

Seems issue is with get_collection so it's switching to creating new one. Here: https:/crewAIInc/crewAI/blob/main/src/crewai/memory/storage/rag_storage.py#L56
