Pyzotero.dump() not working. Response: Not found

[Tomptez]

Hello, for some reason pyzotero.dump() stopped working for me. The file definitely exists in the library. I am using the lates version of pyzotero.

I tried using

with open('article.pdf', 'wb') as f:
    f.write(zot.file())

instead but it didn't work either

Platform: Fedora 39
Python version: 3.12.2
Pyzotero version: 1.5.18

Problem Description

• What were you trying to do?
  I was trying to download a pdf file from a collection
  • What API call did it involve
    pyzotero.dump()
  • What error was raised?
    See below

I can't reproduce this: both file() and dump() are working as expected. If you're getting a 404 error that suggests the attachment doesn't exist on the Zotero server, possibly due to a sync issue or typo. Are you sure that you're passing the ID of a file attachment to the file \ dump call? The 404 URL doesn't look correct to me; it should be something like https://api.zotero.org/users/436/items/H3XDWRWX?format=json&limit=100

Hm, not sure where to go from here.

The code has worked previously, I haven't made any changes, but of course some sync issues could be part of that.

But I can access said attachment via the api.

This URL I can access via my browser:

https://api.zotero.org/groups/2364338/items/MC44N87M/

But using the pyzotero.dump() call it seems to call:

https://api.zotero.org/groups/2364338/items/MC44N87M/file

which produces the 404 error.

I create the zotero instance like this:

zot = zotero.Zotero(libraryID, "group", APIkey)

and try to get the pdfs like this:

attachments = zot.children(articleID)

    for each in attachments:
        try:
            if each["data"]["itemType"] == "attachment":
                if each["data"]["contentType"] == 'application/pdf':
                    pdfID = each["data"]["key"]
                    zot.dump(pdfID)

and I think that code is working, as I can access the attachment via the API. It is just that the /file call is producing the 404 error.
