You have an issue with the variable metadata in your main script.

Thank you, I will give it a look asap. Can you send me the pdf file that generates this error?

Also, which version of the script you are using? It's possible that this error was already fixed in the version 1.1rc4, but I haven't had time to release an official version yet. Can you try to install pip install pdf2bib==1.1rc4 and check if error still occurs?

Hi,

Thank you for your prompt reply and your suggestion. Sorry I was in a hurry so didn’t explain in much details.

Here you go, all PDFs. Still in a hurry.

I will give a closer look later asap.

Thanks, please let me know also about the version you have.

[Don-Yin]

I used the default pip install, so it should be 1.0.3 as per https://pypi.org/project/pdf2bib/.

thanks.

[MicheleCotrufo]

Thanks. So, as I mentioned in my first post, I think this bug was already fixed in one of the last versions (1.1rc4) https://pypi.org/project/pdf2bib/1.1rc4/ but I hadn't had time yet to craft a final release of it. Can you try to upgrade to 1.1rc4 and check if that error still occurs?

Hello Michele, I also see the same, will test now with 1.1rc4...

@MicheleCotrufo confirming I no longer see this after pip install pdf2bib==1.1rc4
