redis-cli is fine

create redis from docker

docker run -d --name redis_ts3 -p 16379:6379 redis/redis-stack-server
docker exec -it redis_ts3 /bin/bash && redis-cli

Add function without error

127.0.0.1:6379> FUNCTION LOAD "#!lua name=mylib \n redis.register_function('myfunc', function(keys, args) return args[1] end)"
"mylib"
127.0.0.1:6379>

redis-py raise error

import redis

settings = {
    'host': 'localhost',
    'port': 16379,
    'db': 0,
    'password': None,
}

r = redis.Redis(**settings)
r.function_load("#!lua name=mylib2 \n redis.register_function('myfunc2', function(keys, args) return args[1] end)")
