Description
A string property with a minLength > 0 adds a NotBlank constraints and ignores the nullable: true property in the schema.

How to reproduce

    Shop:
      type: object
      properties
        name:
          type: string
          minLength: 1
          nullable: true

Possible Solution
NotBlank constraint got an option called allowNull , which could be used to mitigate this.
