doctrine2 sluggable with field with association

Question

I have ORM:

Something\SomeBundle\Entity\MyTable:
type: entity
table: my_table_name
id:
    id:
        type: bigint
        id: true
        generator:
            strategy: AUTO
fields:
    name:
        type: string
        length: '64'
        nullable: true
    slug:
        type: string
        length: '255'
        nullable: true
        gedmo:
            slug:
                separator: -
                style: default
                updatable: false
                fields:
                    - master
                    - name
manyToOne:
    master:
        targetEntity: Master
        joinColumn:
            name: master_id
            referencedColumnName: id

but this doesn't work on prod environment (error: Unable to find slug [master] as mapped property in entity - Something\SomeBundle\Entity\MyTable). Why? How to fix it?

I have a solution if someone else has the same problem

Something\SomeBundle\Entity\MyTable:
  type: entity
  table: my_table_name
  id:
    id:
      type: bigint
      id: true
      generator:
        strategy: AUTO
  fields:
    name:
      type: string
      length: '64'
      nullable: true
    slug:
      type: string
      length: '255'
      nullable: true
      gedmo:
        slug:
            handlers:
                'Gedmo\Sluggable\Handler\RelativeSlugHandler':
                    relationField: master
                    relationSlugField: id
                    separator: -
            separator: -
            style: default
            updatable: false
            fields:
                - name
  manyToOne:
    master:
      targetEntity: Master
      joinColumn:
        name: master_id
        referencedColumnName: id
