Redis Exception on Data types

[mjibril]

I keep getting,

redis.exceptions.DataError: Invalid input of type: 'list'. Convert to a byte, string or number first

on a function

@ring.redis(redis_client,key_prefix="api")
def find(self,source,destination):

where source is a python list of integers.

@ring.lru works fine though. Could it be that ring.redis is not converting function arguments or return values to data types acceptable to redis?

The exception is raised in redis/connection.py", line 118, in encode

It sounds like a bug. every input/output is intended to be converted to bytes.

do you have small reproducible code example about this bug?

[mjibril]

import ring
import redis

redis_client=redis.Redis()

@ring.redis(redis_client,key_prefix="api")
def long_running(arg1,arg2):
    return arg1


long_running([1,2],1);

I am using redis==3.3.11 and ring==0.7.3.... and python 3.7.4

[youknowone]

I tried the same code but didn't find any problem.

$ pip freeze | grep redis
redis==3.3.11

$ python --version
Python 3.7.0

python version is slightly different

$ python issue157.py
b'[1, 2]'

Any idea what can be different from yours and mine?

So I checked again and the following exception is raised first,

Traceback (most recent call last):
File "/.../virtual/lib/python3.7/site-packages/ring/func/sync.py", line 48, in get_or_update
