how automatically redis key generated on my server ?

[jignesh-ob]

Laravel Framework 5.4.36

in my server i use the redis server for cache and also use some libraries redis, predis, jwt and zizaco entrus, also see with specific version like bellow in my project composer.json file

"require": {
   "illuminate/redis": "5.4.*",
   "predis/predis": "^1.1",
   "tymon/jwt-auth": "0.5.*",
   "zizaco/entrust": "5.2.x-dev"
},

i attached the screenshot about the fake empty redis key automatically generated and my redis server is going high and i face the issue enter image description here

i try to resolve this issue in my code review and i can't not get solution, so i expected what exactly going on this issue, how and when it's created fake redis key with empty data

so how can i solve it?

thank you
