url params ignored and used as query params after proto generation

[marcomichelotti]

After writing this sample proto
item.proto

syntax = "proto3";

package name;

// libraries
import "google/api/annotations.proto";
import "protobuf_pydantic_gen/pydantic.proto";

// dtos
import "item_dto.proto";

service ItemService {
  rpc GetItem (GetItemRequest) returns (GetItemResponse) {
    option (google.api.http) = {
      get: "/api/v1/item/{id}"
    };
  };
}

message GetItemRequest {
  int32 id = 1 [(pydantic.field) = {
    description: "The ID of the item to retrieve",
    required: true
  }];
}

message GetItemResponse {
  string message = 1 [(pydantic.field) = {
    description: "The message returned in the response",
    default: ""
  }];
  Item item = 2 [(pydantic.field) = {
    description: "The item returned in the response",
    required: true
  }];
}

item_dto.proto

syntax = "proto3";

package name;

import "protobuf_pydantic_gen/pydantic.proto";


message Item {
  int32 id = 1 [(pydantic.field) = {description: "Name of the item"}];
  string name = 2 [(pydantic.field) = {description: "Name of the item"}];
}

and compiled the proto with:

poetry run python -m grpc_tools.protoc \
		-I ./proto \
		--plugin=protoc-gen-custom=protobuf_pydantic_gen/main.py \
		--python_out=./app/pb \
		--pyi_out=./app/pb \
		--grpc_python_out=./app/pb  \
		--pydantic_out=./app/pb \
		./proto/*.proto

the accepted url for the controller gets: /api/v1/item/{id}?id=1
but it should be: /api/v1/item/1
