TypeError: Argument must be bytes or unicode, got 'list' when making svg #290

Closed hoIIer closed 1 year ago

hoIIer commented 1 year ago

The following previously working code just started breaking with no changes on my end:

import qrcode
import qrcode.image.svg

def make_qr(code_id):
    qr = qrcode.QRCode(image_factory=qrcode.image.svg.SvgPathImage)
    qr.add_data('https://foo.com?code={code_id}')
    qr.make(fit=True)
    img = qr.make_image()

code_id is a uuid string e.g. code_id = 'eefea63f-ca20-478a-b911-3303ada87832'

stack trace:

>>> img = qr.make_image()
