Model.find() is giving error

[muslih-DIY]

class HashModelExtended(HashModel, abc.ABC):

    __primary_key_pattern__ = "{pk}"

    def __init__(self, **data: Any) -> None:
        pk = self.__primary_key_pattern__.format(**data)
        super().__init__(**data, pk=pk)

    @classmethod
    def pk_generate(cls, **data):
        return cls.__primary_key_pattern__.format(**data)



class AgentDevice(HashModelExtended):
    username: str
    callcenter: int = Field(index=True)
    endpoint: int = Field(index=True)
    agent_id: int = Field(index=True)
    ipaddress: Optional[str]
    status: Optional[str]

    __primary_key_pattern__ = "{callcenter}:{endpoint}"

    class Meta:
        global_key_prefix = "agent"
        model_key_prefix = "device"
        primary_key_pattern = "{pk}"
        index_name = "agentdevice-index"

here is the program i was trying after declaring the model

print(AgentDevice.find(AgentDevice.callcenter == 1))

this part of the program is causing the issue

redis-om-python/aredis_om/checks.py

Line 9 in 1213ca7

cmd_info = await conn.execute_command("command", "info", cmd)

i was working with redis_om not aredis_om

from functools import lru_cache
from typing import List

from redis_om.connections import get_redis_connection


@lru_cache(maxsize=None)
def check_for_command(conn, cmd):
    cmd_info = conn.execute_command("command","info" ,cmd)
    return None not in cmd_info


@lru_cache(maxsize=None)
def has_redis_json(conn=None):
    if conn is None:
        conn = get_redis_connection()
    command_exists = check_for_command(conn, "json.set")
    return command_exists


@lru_cache(maxsize=None)
def has_redisearch(conn=None):
    if conn is None:
        conn = get_redis_connection()
    if has_redis_json(conn):
        return True
    command_exists = check_for_command(conn, "ft.search")
    return command_exists

@uglide
if it is works, please create and merge this issue

this may also solve #532

This sounds like a Redis Versioning / ACL issue - are you using a version of Redis with COMMAND INFO and one where you've given the client permission to use the COMMAND INFO command?

Going to close this issue to tidy up (think it's an ACL issue) if the issue persists please feel free to reopen.
