I use this code` @ShopifyDevSup 

const freshFileObj = await this.getFileInfos(file.path);

const response = await axios.get(freshFileObj.download_url);

const asset = new this.shopifyApi.rest.Asset({ session: this.session });

    asset.theme_id = liveTheme.id;

    asset.key = freshFileObj.path;

    asset.value = response.data;

    await asset.save({

      update: true,

    });
