redis.exceptions.ResponseError: unknown command 'module'

[therealbazzi]

Hi,

So basically trying to reproduce what @simonprickett did here except that i'm doing it on Redis cloud instead of locally or using a venv or docker or whatever.

So i've managed to successfully write to the redis db cloud after properly configuring REDIS_OM_URL to point at the proper endpoint x credentials, now when I perform a rediSearch query ex:
Adoptable.find(Adoptable.name == "Poppy").all()
I get the error
redis.exceptions.ResponseError: unknown command 'module'
Another way of reproducing the above is as follows:

from redis import ResponseError
try:
    Adoptable.find(Adoptable.name == "Poppy").all()
except ResponseError as e:
    print(e)

I've googled the above type of error but all i see is the same type of error but the word 'module' being swapped by different terms (ex: like JSON.GET whose solution was to include redisJSON)
Any help is appreciated, thank you.

PS: yes i have created my database by properly including modules rediSearch and redisJSON.

@therealbazzi Hi there - I'm able to reproduce this, looks like the issue occurs because it's trying to call the MODULE LIST command in the Python library somewhere, and that's not available on Redis Enterprise. You can see this by trying to do the same thing in RedisInsight or redis-cli (see screenshot below). I'll dig into why it's doing this and see what we can do.

thanks @simonprickett - looks like you forgot to attach your screenshot ^^

Looks like the code here relies on MODULE LIST to determine which modules are installed in the Redis server... I don't think that's going to work on Enterprise.

Suggesting this be changed to determine if RediSearch and RedisJSON modules are installed using the COMMAND command e.g.:

COMMAND INFO FT.SEARCH
1) 1) "FT.SEARCH"
   2) -1
   3) 1) "readonly"
   4) 1
   5) 1
   6) 1
   7) (empty list or set)

and

COMMAND INFO JSON.SET
1) 1) "json.set"
   2) -1
   3) 1) "write"
      2) "denyoom"
   4) 1
   5) 1
   6) 1
   7) (empty list or set)

If the modules aren't installed, these commands will return a NIL response:

COMMAND INFO JSON.SET
1) (nil)

@therealbazzi I'll get a pull request together to make this change that should fix this on Redis Enterprise. Meantime I suggest you proceed with software development using Docker until this is released.

Oops so I did - here's what I mean :)

Hi @simonprickett thanks a lot.
I went for the docker suggestion..
OK i got docker up and running w/ localhost and port 6379 ..
I could write to redis db (i see changes on redisInsight) all is good.
Problem is now when i want to query, ex:
Adoptable.find(Adoptable.name == "Poppy").all()
gives
redis_om.model.model.RedisModelError: Your Redis instance does not have either the RediSearch module or RedisJSON module installed. Querying requires that your Redis instance has one of these modules installed.
I know there's a config I messed up somewhere maybe .. hope you can help w/ this .. thank u

PS: I've also followed (hopefully) the same steps in your blog
Im assuming i have to include somewhere modules RedisJSON/RediSearch, but how to do that ?

[simonprickett]

@therealbazzi to get going with the right modules installed you can use the Docker Compose file here that uses the redisearch container... when using the edge version of that you'll get both modules installed for you with no further config needed.

[therealbazzi]

Docker Compose file here

I am using the docker compose that you link, but i still get the same issue.

Docker Compose file here

Are you connecting to Redis at localhost:6379? Unset any REDIS_OM_URL environment variables to make sure. I just checked and my example from my repo works using that Docker Compose file.

[therealbazzi]

REDIS_OM_URL

echo $REDIS_OM_URL
gives
redis://@127.0.0.1:6379
I have set this manually .. Also tried to unset on terminal as
unset REDIS_OM_URL still same error

PS: Yes docker is running on localhost:6379 and is writing properly on the redis db on RedisInsight (i see that).
PSS: I've changed to REDIS_OM_URL to
export REDIS_OM_URL=redis://@localhost:6379/
still doesn't work

echo $REDIS_OM_URL gives redis://@127.0.0.1:6379 I have set this manually .. Also tried to unset on terminal as unset REDIS_OM_URL still same error

Can you share a project repo URL that I can look at and try and reproduce?

Also try stopping all the containers with docker ps then docker stop <id>, and restart using my Docker Compose. That will make sure the right container's on 6379.

[therealbazzi]

Oh now it works. !! Thanks a lot @simonprickett .. I had to kill all ports running 6379 (had like 5 running for no reason or maybe because i did something previously on my laptop like redis-server start)

Thanks a lot man !

@therealbazzi this should be fixed in version 0.0.17 that I just released: https://pypi.org/project/redis-om/0.0.17/ [updated to say v 17 not 16]
