Hey!

I have a question to this beautiful peace of software ... I don't know if its an issue with Jaris Fork or in the main branch but as i am lacking python knowledge i humble ask anyways:

/vacdec/vacdec --image-file /tmp/gettinger_v3.png

Traceback (most recent call last): File "/vacdec/vacdec", line 241, in main() File "/vacdec/vacdec", line 228, in main covid_cert_data = data[0].data.decode() IndexError: list index out of range

Can anyone give me a hint why this certificate shows that error please?

Kind regards Martin

This likely just means your QR code is either not an EU certificate (some countries issue their own certificates in a different format) or the picture quality is not good enough to properly read the QR code.

I can check if you send me the certificate via mail.

Thanky you sir - This would be really really helpful!

I have two versions - the QR Code alone and the original official certificate. Austrian Greencheck app validates both correctly. May i kindly ask you for an email address as these are not my personal certificates and i do not want to attach them on this platform ...

Clarified via email, was just an image quality issue, pyzbar was unable to decode.
