Strange. That was the error I was getting before I used the web token as per spicefather's instructions, but it is working now.

Just tried it again to download the "Guardian Weekly" to confirm it is still working.

I am still getting the key error.

I have tried entering new code in the json file again (several times), restarting my computer, I also tried generating a new code for the plugin from Libby. Same result - each time I try to download a magazine, I get the key error.

I can right-click on the magazine in my list of loans inside the plugin, so I know that part is working fine. It just will not download. I even tried a Guardian Weekly as that worked in your case.

Is it possible the plugin or Libby are looking for a magazine but the magazine has been given a different key property, something like that? (NB books work fine for me).

Here is my error message:

Hoping someone can see what is going on in my plugin - sometimes it calls a magazine an ebook, maybe that is something to do with it?
It also does not like openbook = self.send_request(meta["urls"]["openbook"])

Could it maybe be looking for "openmagazine" in the square braces? Or maybe openbook on the left side of the assignment should be openmagazine?

Just putting it out there, as do not know the code behind all this.

That's my experience as well.

Adding my two cents here that I too am receiving the HTTP 403 error and the plugin is currently unusable.

There's already a solution. Read the page before this one.

No, openbook is correct.

When you download a magazine it sends a request to overdrive and you should get a response that looks like

{
  "urls": {
    "web": "https://dewey-c5a399a962cbe1bfd566f164d6158f5d.read.libbyshelf.com/",
    "openbook": "https://dewey-c5a399a962cbe1bfd566f164d6158f5d.read.libbyshelf.com/_d/openbook.json",
    "rosters": "https://dewey-c5a399a962cbe1bfd566f164d6158f5d.read.libbyshelf.com/_d/roster.json",
    "possession": "https://dewey-c5a399a962cbe1bfd566f164d6158f5d.read.libbyshelf.com/_d/possession",
    "activity": "https://dewey-c5a399a962cbe1bfd566f164d6158f5d.read.libbyshelf.com/_d/activity"
  },
  "message": ".....",
  "bankscope": "title-c5a399a96",
  "expires": 1716422399
}

(I've left out the message part and formatted it to make it more readable)

However if you don't have the correct id/token, then you get a response like

{
  "urls": {
    "web": "https://dewey-c5a399a962cbe1bfd566f164d6158f5d.read.libbyapp.com/",
    "possession": "https://dewey-c5a399a962cbe1bfd566f164d6158f5d.read.libbyapp.com/_d/possession",
    "activity": "https://dewey-c5a399a962cbe1bfd566f164d6158f5d.read.libbyapp.com/_d/activity"
  },
  "message": ".....,
  "bankscope": "title-c5a399a96",
  "expires": 1716422399
}

which is missing the two important bits openbook and rosters.
Hence the plugin crashes when it tries to read the value of meta["urls"]["openbook"]

Thanks - I am in the python code behind the scenes and reviewing the lines of the files quoted in my error response. But I can't find where to get the code you posted above with the url object etc. Can you please tell me where I can find this?

Thanks so much

The plugin does not display capture the requests and responses unless you are running in debug mode. (In windows, you can press Ctrl-Shift-R to restart in debug-mode and when you close down, calibre will open the log in notepad)


The relevant lines of code are from https://github.com/ping/libby-calibr...client.py#L820

    
        download_base, meta = self.prepare_loan(loan)
        # contains nav/toc and spine, manifest
        openbook = self.send_request(meta["urls"]["openbook"])
        rosters: List[Dict] = self.send_request(meta["urls"]["rosters"])

The first line 820 calls self.prepare_loan(loan) and this fires a request to overdrive. If you are running in debug mode you should see a line starting with

[overdrive_libby/0.1.9] REQUEST: GET https://sentry-read.svc.overdrive.com/open/magazine/card/

followed a few lines later by a line starting

[overdrive_libby/0.1.9] RESPONSE: 200 https://sentry-read.svc.overdrive.com/open/magazine/card/

This has a few lines of headers and then the body which will start with a line like

[overdrive_libby/0.1.9] RES BODY: {"urls":{"web":

It is this body that is assigned to the variable meta on line 820 and of course if the body does not have a url for openbook then line 822 will blow up.

Unfortunately, the solution mentioned hasn't worked for many of us.

Correct, it didn't work for me.

It doesn't work for downloading magazines.
Other features are back normally.

You can underline magazines all you want, it's not working for anything. It isn't the developer's fault that it isn't, but giving the impression it is when it isn't doesn't help anyone.

Downloading books, managing holds, managing cards, etc works with the new temporary fix. So how come you said it's not working for anything? It only doesn't work for magazines. All other features still work. I rest my case.
