{
loadDocumentEntity = GetLoadDocumentEntity(loadAllPages, documentGuid, fileCacheSubFolder, pngViewer);
}
}
return loadDocumentEntity;
}
private static LoadDocumentEntity GetLoadDocumentEntity(bool loadAllPages, string documentGuid, string fileCacheSubFolder, ICustomViewer customViewer)
{
if (loadAllPages)
{
customViewer.CreateCache();
}
dynamic viewInfo = customViewer.GetViewer().GetViewInfo(ViewInfoOptions.ForHtmlView());
LoadDocumentEntity loadDocumentEntity = new LoadDocumentEntity();
if (!Directory.Exists(cachePath))

}

foreach (Page page in viewInfo.Pages)
{
PageDescriptionEntity pageData = GetPageInfo(page, pagesInfoPath);
if (loadAllPages)
{
pageData.SetData(GetPageContent(page.Number, documentGuid, cachePath, "N"));
}
loadDocumentEntity.SetPages(pageData);
}
loadDocumentEntity.SetGuid(documentGuid);
return loadDocumentEntity;
}
on this line → dynamic viewInfo = customViewer.GetViewer().GetViewInfo(ViewInfoOptions.ForHtmlView());
I have checked it and the error is coming on word file and it is working on pdf file.
