Error while unserialization of model - php

Question

on my production system occurs an error while unserializing an user object within queue execution:
[2016-12-20 21:10:01] production.ERROR: Illuminate\Database\Eloquent\ModelNotFoundException: No query results for model [App\User]. in /var/www/virtual/bob/bobnet/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Builder.php:210
Stack trace:
#0 /var/www/virtual/bob/bobnet/vendor/laravel/framework/src/Illuminate/Queue/SerializesAndRestoresModelIdentifiers.php(45): Illuminate\Database\Eloquent\Builder->findOrFail(137)
If I run
\App\User::findOrFail(137)
the correct user could is found without an error. Until a few weeks everything worked fine. Just as the unserialization on my dev system.
Has anyone an idea what's going wrong?

Answer 1

Long story short:
Due to some environment variables and execution context the queue was worked with a different php version which resulted in this error. After forcing the correct php version everything works fine.
