Trying to access array offset on value of type null

[incoming-th]

• Horizon Version: 5.*
• Laravel Version: ^8.0
• PHP Version: 7.4
• Redis Driver & Version: predis/phpredis ^1.1
• Database Driver & Version: MySQL 8

Description:

Got this error message randomly (not very helpful I know but that's really what is happening) on my logs:

Trying to access array offset on value of type null {"exception":"[object] (ErrorException(code: 0): Trying to access array offset on value of type null at /home/forge/xxx/releases/20210322152436/vendor/laravel/horizon/src/JobPayload.php:48)

I deduct this is a connection issue between the server and the Redis (separate servers in different datacenter), but when I try to connect with telnet from the server with horizon daemon to Redis I have no connection issue.

Hoping to see if someone already have this kind of issue.

Steps To Reproduce:

I tried to reproduce this without success, it is appearing randomly every 2 days or week nothing was done on the instance, same code no change.

The only thing I can think of is that horizon daemon is in different datacenter than the Redis server, and could be a timeout issue - but again no problem at all when using telnel.

Here is a screenshot, it could help to debug:

Hi @MickaelTH please look at #924 It has already been discussed there heavily and its the same issue you're having if i am not mistaken.
