Using a DTO throws a 500 validation exception












0














Following the documentation How to Use a DTO for Writing, I'm getting a 500 validation error:



{
"@context": "/api/contexts/Error",
"@type": "hydra:Error",
"hydra:title": "An error occurred",
"hydra:description": "Cannot validate values of type "NULL" automatically. Please provide a constraint.",
...


The DTO is the same as documented (note the specific namespace):



namespace AcmeInfrastructureDto;

use ApiPlatformCoreAnnotationApiResource;
use SymfonyComponentValidatorConstraints as Assert;

/**
* @ApiResource(
* collectionOperations={
* "post"={
* "path"="/do-something",
* },
* },
* itemOperations={},
* )
*/
final class DoSomethingRequest
{
/**
* @AssertNotBlank
* @AssertEmail
*/
public $email;
}


Here's the configuration:



# api_platform.yaml
api_platform:
mapping:
paths:
- '%kernel.project_dir%/src/Infrastructure/Dto'

  • Is your top level namespace really Acme?

  • Yes, the namespace has been changed from the default one to the name of the organization.

Actually, I was calling the endpoint sending FormData encoded payload. It turns out that "API Platform only supports raw documents as request input" (cf. https://api-platform.com/docs/core/form-data/).



Nevertheless, I believe that would be nice to throw a more explicit exception in this case than letting the RecursiveContextualValidator of Symfony handle the case with an obscure message.
