OpenApiFactory is losing 4xx response content when using `output: false`

[VincentLanglet]

API Platform version(s) affected: 4.2

Description
When writing the following route

new Post(
            uriTemplate: '/foo',
            status: 202,
            security: "is_granted('foo', object)",
            input: FooInput::class
            output: false,
            processor: FooProcessor::class,
        ),

I expect

• That my route could send 422 in case of validation error of FooInput, with the list of the validation error.
• That my route could send 400 in case of invalid input
• That my route could send 403 in case of missing rights
• That my route could return a 202 without content in case of success.

I DO get this behavior, ie

• A 202 returns an empty content
• A 422 returns the list of violations

BUT the schema generated is

"202": {
    "description": "Foo",
    "links": {}
},
"400": {
    "description": "Invalid input",
    "links": {}
},
"422": {
    "description": "An error occurred",
    "links": {}
},
"403": {
    "description": "Forbidden",
    "links": {}
}

instead of classics

"422": {
    "description": "An error occurred",
    "content": {
        "application/ld+json": {
            "schema": {
                "$ref": "#/components/schemas/ConstraintViolation.jsonld"
            }
        },
        "application/problem+json": {
            "schema": {
                "$ref": "#/components/schemas/ConstraintViolation"
            }
        },
        "application/json": {
            "schema": {
                "$ref": "#/components/schemas/ConstraintViolation"
            }
        }
    },
    "links": {}
},

I think it's related to your change in #7384 @soyuka
If I remove the !$noOutput in

core/src/OpenApi/Factory/OpenApiFactory.php

Line 511 in c8493bb

if (null === $response->getContent() && $responseMimeTypes && $operationOutputSchemas && !$noOutput) {

I get back my content and schema.

But I also get

 "202": {
    "description": "User resource created",
    "content": {
        "application/json": {
            "schema": {}
        },
        "application/ld+json": {
            "schema": {}
        }
    },
    "links": {}
},

which was maybe what you wanted to avoid.

I thought about two easy solutions:

• Either check the status code (but could be weird if someone create a POST with a non 2xx status code)

• Either add a bool isError to the buildOpenApiResponse and pass true here
  

  core/src/OpenApi/Factory/OpenApiFactory.php

  Line 1014 in c8493bb

  $operation = $this->buildOpenApiResponse($operation->getResponses() ?: [], $status, $errorResource->getDescription() ?? '', $operation, $originalOperation, $responseMimeTypes, $operationErrorSchemas, $resourceMetadataCollection);
