          series_id: ID,
          title: item.title,
        });
        if (seasonResponse.status === 200) {
          item.episodes.forEach(async (e) => {
            try {
              // uploading video
              if (e.file) {
                await uploadingVideos(e, seasonResponse.data.data);
              }
              // upload episode Without video
              else {
                const { status, data } =
                  await patchAppendEpisodeToSeasonOfSeries({
                    season_id: seasonResponse.data.data.id,
                    title: e.title,
                    imdb_id: e.imdb_id,
                    content_url: "",
                  });
                if (status === 200) {
                  console.log("OK");
                }
              }
            } catch (error) {
              console.error(error);
            }
          });
        }
      } catch (err) {
        console.error(err);
      }
    });
  };
