有一个Offer实体

* @ApiResource(
 *     normalizationContext={"groups"={"offer:read"}, "swagger_definition_name"="Read"},
 *     denormalizationContext={"groups"={"offer:write"}, "swagger_definition_name"="Write"},
 *     itemOperations={
 *         "get",
 *         "put"={"security"="is_granted('ROLE_USER')"},
 *         "delete": {
 *             "security"="is_granted('ROLE_USER')"
 *         }
 *     },
 *     collectionOperations={
 *          "get",
 *          "post"={
 *              "security"="is_granted('ROLE_USER')"
 *          }
 *     },
 *     attributes={
 *          "order"={"id": "DESC"}
 *     },
 * )
class Offer
{
...

    /**

     *      inverseJoinColumns={@JoinColumn(name="country_id", referencedColumnName="id")}
     * )
     * @Assert\NotBlank
     * @Assert\NotNull

     * @ApiSubresource(maxDepth=1000)
     */
    private Collection $countries;

    /**
     * @return Country[]|ArrayCollection<Country>
     */
    public function getCountries()
    {
        return $this->countries;
    }

    /**
     * @param Country $country
     * @return $this
     */
    public function addCountry(Country $country): self
    {
        if (!$this->countries->contains($country)) {
            $this->countries->add($country);
        }

        return $this;
    }
  ...
}

使用诸如https://example.com/api/offers/1 "countries": ["/api/countries/10"] 之类的 PUT 请求 ，将 ID 为 10 的国家/地区添加到现有国家/地区。告诉我出了什么问题。谢谢
