Create a custom route for a collection using GET method - php

Question

I do not manage to create a custom route for a collection, my entity is named File.
here is my Entity annotation :
/**
* #ApiResource(
*
* normalizationContext={"groups"={"file"},"enable_max_depth"=true},
* denormalizationContext={"groups"={"file-write-customers"},"enable_max_depth"=true},
* attributes={"force_eager"=false},
* itemOperations={
* "get",
* "put",
* "get_mandate_pdf"={
* "method"="POST",
* "path"="/files/{id}/mandate-pdf",
* "controller"=FileCreatePdfController::class,
* },
* },
* collectionOperations={
* "stats"={
* "method"="GET",
* "path"="/files/stats",
* "controller"=FileStatsController::class,
* }
* },
* )
* #ApiFilter(SearchFilter::class, properties={"status": "exact", "sponsor": "exact"})
* #ApiFilter(DateFilter::class, properties={"updatedAt"})
* #ORM\Entity
* #ORM\Table(name="cases")
*/
The controller file
<?php
namespace App\Controller;
use App\Entity\File;
class FileStatsController
{
public function __invoke(File $data): File
{
return $data;
}
}
however i have this error when i reach /files/stats, it seems that api plaform is expecting an Id .
For some reasons if i switch the method from GET to POST the route is working
{
"#context": "\/contexts\/Error",
"#type": "hydra:Error",
"hydra:title": "An error occurred",
"hydra:description": "The identifier id is missing for a query of App\\Entity\\File",
"trace": [
{
"namespace": "",
"short_class": "",
"class": "",
"type": "",
"function": "",
"file": "\/srv\/api\/vendor\/doctrine\/orm\/lib\/Doctrine\/ORM\/ORMException.php",
"line": 309,
"args": []
},

Answer 1

I manage to find the solution , in my Controller if i remove the typed variable $data
namespace App\Controller;
class FileStatsController
{
public function __invoke($data)
{
return $data;
}
}
I manage to properly retreive the data
in addition, the method get is mandatory in the ApiRessource annotations
collectionOperations={
"get",
* "stats"={
* "method"="GET",
* "path"="/stats",
* "controller"=FileStatsController::class,
* }
* }
