Api-platform PUT operation with denormalization_context groups on an itemOperations not working

I have 2 entities:

I wanted to retrieve only words for itemOperation and not for collectionOperations so i added a group GET "item_words.read" and for PUT denormalization_context.

It is perfectly working for GET operation, for some reason the PUT operation is not giving me the “words” subresource.

GET :

PUT :

Here is my code :

Answer

After digging for a while , to make it works the "method" must be present on the operation

He is the working annotation

/**
 * @ApiResource(
 *     normalizationContext={"groups"={"item.read"}},
 *     denormalizationContext={"groups"={"item.write"}},
 *     collectionOperations={"get", "post"},
 *     itemOperations={
 *          "get"={
 *              "method"="GET",
 *              "normalization_context"={"groups"={"item.read","item_words.read"}},
 *          },
 *          "put"={
 *              "method"="PUT",
 *              "normalization_context"={"groups"={"item.write", "item_words.write"}},
 *          },
 *         "delete",
 *         "getItemVocabulary"={
 *                   "method"="GET",
 *                   "path"="/items/{id}/vocabulary",
 *                   "controller"=ItemVocabularyController::class,
 *                  }
 *     }
 * )
 * @ORMEntity
 * @ORMTable(name="`items`")
