Describe the bug
I'm currently getting a HTTP 500 with the body Object reference not set to an instance of an object.. This happens when fetching a single ticket using ticket(), but fetching multiple tickets using tickets() works fine. I'm not sure whether this is an issue of this library or of the actual Lidl API.

Expected behavior
ticket() actually returns a valid response.

Environment:

• Python-Version: 3.12.2
• Release-Version: 0.3.5
• OS: Windows 11
• Browser: Firefox
• Country: cs
