ERROR: ERR wrong number of arguments for 'mget' command

@DavidNineRoc
What is the reason for this error?
Redis is installed and running in the local environment, and access is normal;

local.ERROR: ERR wrong number of arguments for 'mget' command {"userId":1,"email":"david@qq.com","exception":"[object] (Predis\Response\ServerException(code: 0): ERR wrong number of arguments for 'mget' command at /var/www/monday/v-shopendor/predis/predis/src/Client.php:370)

My redis running environment and testing are normal, the client can also execute commands normally after the connection, the process and port are also normal.
I think the problem should be here，“ \Redis::set” and “\Redis::lpush ()”
the model did not place data at boot，then causes the key-value pair data to be empty when the page is loaded.

How can I solve it?

This problem is because I did not judge the empty array when I took redis value. I have fixed this problem. Thank you for your issue
