I am using Redis connection for mem0 for my Telegram bot:

from config import redis_url

redis_url = f"redis://default:{settings.REDIS_PASSWORD}@{settings.REDIS_HOST}:{settings.REDIS_PORT}/0"

memoryConfig = {
    "vector_store": {
        "provider": "redis",
        "config": {
            "collection_name": "mem0",
            "embedding_model_dims": 1536,
            "redis_url": redis_url
        }
    },
    "version": "v1.1"
}

memory = Memory.from_config(memoryConfig)

And get this error:

is deprecated and will be removed in the next major release. Pass connection parameters in __init__.
  return vector_store_instance(**config)

Does anyone have any idea how this can be solved?

I'm not 100% sure about this, but it seems it's complaining that your Redis instance doesn't include the correct version of the Redis search module (2.6.0+) or any search module at all. I looked at the Mem0 site briefly, and one of the examples I saw there show Redis Stack as a prerequisite, installed using Docker.

You can check if your instance of Redis Stack includes the search module by running the INFO command using the Redis CLI (redis-cli). You should see something like the following in the output.

# Modules
module:name=bf,ver=20805,api=1,filters=0,usedby=[],using=[],options=[]
module:name=timeseries,ver=11205,api=1,filters=0,usedby=[],using=[],options=[]
module:name=ReJSON,ver=20808,api=1,filters=0,usedby=[search],using=[],options=[handle-io-errors]
module:name=RedisCompat,ver=1,api=1,filters=0,usedby=[],using=[],options=[]
module:name=search,ver=21012,api=1,filters=0,usedby=[],using=[ReJSON],options=[handle-io-errors] <-- search info
module:name=redisgears_2,ver=20020,api=1,filters=0,usedby=[],using=[],options=[]

You might also try asking your question in our Discord channel. There are lots of helpful folks there who can help.

In the end, I decided to use supabase for this task. After asking the people at Discord, they told me that I was having problems installing redis, which is most likely the case, so I think the problem can be considered closed.
