It has successfully claimed the book from the newsletter already, but on subsequent days I'm getting the above error.

And it sends an IFTTT notification for the second one :(

Updated to the latest code from master of this repo. Issue still present.

Can confirm, I'll look into it. For a quickfix, create a file named "lastNewsletterUrl" containing "https://www.packtpub.com/packt/free-ebook/practical-data-analysis" in the config folder. This should stop the errors for now.

[juzim]

Fixed in #48

[lucymhdavies]

nice. thanks 👍

[juzim]

Yes, this is the same error. The fix should be merged tonight hopefully or you can change the line yourself.

[trancen]

Sorry just noticed the comment above about created the "lastNewsletterUrl" that worked.

[niqdev]

Thanks @juzim , the problem above is fixed, but actually there is a bug, see the log below (I've hidden some variables/paths)

• upload 2 times the ebook from the newsletter with 2 different name (but the file is the same)
• I received 2 email, the first one is correct, the second again contains 2 link with 2 pdf but are the same

python script/spider.py -c config/prod.cfg -u drive -s firebase -n gmail

[niqdev]

Actually I started the script again and it seems that the 3 book are identical and the daily ebook is ignored and I have 3 copy of the same book (newsletter). Moreover I checked on firebase and the data uploaded are mixed e.g. different filename but same author (of the newsletter).

[juzim]

I think we have to reset the Packtpub instance before handling the newsletter but then this would have been broken for weeks. Could you check?

Also, could you comment out spider.py:22 so we can see the contents of each handled packtpub.info?

[niqdev]

Yep,
so first log (see the author is wrong) and noticed now paths is empty

[niqdev]

About the first question, we probably have to reset everything before a new claim, but is this the first newsletter since they reactiveted the free ebook? The other books seems correct, I checked also the logs on heroku

[niqdev]

Also the field url_source_code is wrong

[juzim]

Can you add packtpub = Packtpub(config, args.dev) to spider.py:123 and see if it fixes it? Sorry, but somehow the tests on my machine are broken...

[juzim]

Did you by any chance delete the lastNewsletterUrl file? Because if the script tries to grab an already claimed newsletter book from the archive, it won't find it on the top position and overwrite the data for whatever book is currently on there.

We have to either check if the book was already claimed (would be a nice feature anyways) or find the book in the list by name/id/etc.

I'll try to look into it tomorrow but it shouldn't happen again unless you delete the file.
