我正在尝试在媒体中输入图像以进行与电子邮件模板相关的自定义，如下所示：
$contentCatalog=ContentCatalog_en
$contentCV=catalogVersion(CatalogVersion.catalog(Catalog.id[default=$contentCatalog]),CatalogVersion.version[default=Staged])[default=$contentCatalog:Staged]
$jarResourceCms=jar:com.test.core.setup.CoreSystemSetup&/core/import/cockpits/cmscockpit
INSERT_UPDATE Media;$contentCV[unique=true];code[unique=true];mime;realfilename;@media[translator=de.hybris.platform.impex.jalo.media.MediaDataTranslator][forceWrite=true]
;;EmailPageModel_preview;text/gif;EmailPageModel_preview.gif;$jarResourceCms/preview-images/EmailPageModel_preview.gif
但是，在尝试导入 impex 的这一部分时，我一直在日志中收到以下错误。
