Describe the bug
When using a Redis cluster and saving a model with the Cacheable trait a CROSSSLOT Keys in request don't hash to the same slot error is thrown.

Eloquent Query
Please provide the complete eloquent query that caused the bug, for example:


250            // let's log that that it was attempted.
251            $schema = $this->modelInspector->inspect($entity::class);
252            $attribute = collect($schema['attributes'])->where('name', $relationship->getForeignKeyName())->first();
253            if ($attribute && $attribute['nullable']) {
254                $relationship->dissociate();
255                $entity->save();
256
257                return;
258            }

Environment

  • PHP: 8.3.3
  • OS: Alpine Linux 3.23
  • Laravel: 12.56
  • Model Caching: 13.1.1

Additional context
We do have a BaseModel which is where we've set the Cacheable trait, that most of our models extend from. It also seems like the error is occurring when saving/syncing relationships.
