Hi Guys,
In a new shopware installation with version 5.5.10, we are getting an error of „Failed to create the attribute models, please check the permissions of the ‚/html/authenticblonde\_alt/var/cache/production\_\*\*\*\*\*\*/doctrine/attributes/‘ directory“.
Situation is when creating configuration option from the backend.
I selected a configuration group and and add configuration option, and the above error occured in the console.
I have tried following,
1. Given even full permission (777) to var folder
1. Removed production\_\*\*\*\* folder and cache cleared.
2. Run repainred php script from the shopware. (Use in the 5.2.\* shopware)
Nothing worked.
What may be the reason?
Thanks in advance

The exact error is as follows,
**Fatal error** : Uncaught Doctrine\ORM\Mapping\MappingException: No mapping found for field ‘configuratorGroup’ on class ‘Shopware\Models\Attribute\ConfiguratorGroup’
Is there any new repair key script available for shopware 5.5.10?
