Zotero 7 Beta: Attachment Preview not updated in some cases

mjthoraval · January 25, 2024

If I select an item with a PDF file attachment, it will correctly show the preview of the main attachment in the Attachments section.
If I switch to an item with an attachment that does not have a preview (djvu file for example), the preview in the Attachments section keeps showing the preview of the previous item.

Let us know if you're still seeing any cases of this after beta 75.

Something strange happening here.
My old .djvu files are identified as image type:

Same icon as a .png file:

But if I use the same file in a new item, it does not get identified as an image file anymore:

Debug ID in Troubleshooting Mode for just clicking on the parent item of the old .djvu file, with the Attachment Preview activated:

[JavaScript Error: "Could not parse path (/C:/Users/mjthoraval/Zotero/storage/PLWI7WWY/2001-Computer_Vision.djvu): NS_ERROR_FILE_UNRECOGNIZED_PATH" {file: "chrome://zotero/content/osfile.mjs" line: 151}]

[...]

Same for doing this with the same file newly added to another item: the error does not appear:
Debug ID: D833793795

So it seems that the problem comes from the wrong type identification in older version?

I forgot to comment on the original problem: I see the problem only with the old .djvu files identified as images.

Start from an item with a PDF file attachment:
https://s3.amazonaws.com/zotero.org/images/forums/u265723/044dsxoq6er90zil2rb3.png

Switch to the old .djvu file -> The Preview is not updated, still showing the one of the previous item:

Click on its attachment:

Switch to the newly added .djvu file -> It is fine now:
