I have an entity with the following column definition: ```php /** * @ORM\Column(name="amount", type="string") */ private string $amount; ``` Now I want to type that property as `numeric-string` because it will only ever contain numbers anyway. ```php /** * @var numeric-string * * @ORM\Column(name="amount", type="string") */ private string $amount; ``` But I'm getting this error: ``` Property MyEntity::$amount type mapping mismatch: database can contain string but property expects string. ``` I don't know how to solve this. Is it even possible? And is the error message correct? Shouldn't it say: ``` Property MyEntity::$amount type mapping mismatch: database can contain string but property expects numeric-string. ```
