Hello,
I was wondering if Long term memory was enabled by default when we activate memory, if it is, how to deactivate it ?
Because in my crew I only use Short term memory and Entity memory but I always have those messages :
- Give Feedback / Get Help: [Sign in to GitHub · GitHub](https://github.com/BerriAI/litellm/issues/new)
- LiteLLM.Info: If you need to debug this error, use `litellm.\_turn\_on\_debug()'.
- Failed to add to long term memory: Failed to convert text into a Pydantic model due to error: litellm.APIError: AzureException APIError - argument of type ‘NoneType’ is not iterable
Here is my config :
```
@crew
def crew(self) -> Crew:
"""Creates the Research Crew"""
# To learn how to add knowledge sources to your crew, check out the documentation:
# https://docs.crewai.com/concepts/knowledge#what-is-knowledge
return Crew(
agents=[
...
],
tasks=[
...
],
process=Process.sequential,
verbose=True,
output_log_file="checking_crew.log",
memory=True,
short_term_memory=ShortTermMemory(
storage=RAGStorage(
embedder_config=EMBEDDER_CONFIG,
type="short_term",
path="src/csc_flow_analyzer/crews/checking_crew/data/stm",
)
),
entity_memory = EntityMemory(
storage=RAGStorage(
embedder_config=EMBEDDER_CONFIG,
type="short_term",
path="src/csc_flow_analyzer/crews/checking_crew/data/em"
)
),
embedder=EMBEDDER_CONFIG,
)
```
And even when I enable litellm.\_turn\_on\_debug(), i have no log related to it so I’m a bit confused

Yes, as far as I understand, all memory types are automatically enabled when you set `memory=True`, just like I mentioned in another thread:
> [@Mem0 + CrewAI User Personalization](https://community.crewai.com/t/mem0-crewai-user-personalization/5257/2):

> Digging into [the `crewai/crew.py` file](https://github.com/crewAIInc/crewAI/blob/main/src/crewai/crew.py), particularly the `create_crew_memory` validator, I noticed that this flag initializes several internal memory components like `ShortTermMemory`, `LongTermMemory`, and `EntityMemory` — even if you only want to use `ExternalMemory`.

As far as I know, there’s currently no way to selectively enable or disable individual memory modules.

So I need to remove it from the validator, right ?

Honestly, I wouldn’t advise modifying a library’s (CrewAI’s) base class unless you’re absolutely certain about everything involved in your changes.
Perhaps a much less risky approach is [opening an issue here](https://github.com/crewAIInc/crewAI/issues).
