@nguyentd01 are you still experiencing this issue? If so:

• What Python version are you using?
• What version/build of ebooklib are you using?
• Looks like you are using Windows, however, which operating system are you using (Win 10, Win 11, etc.)?
• Are you able to supply some context code?
  • Maybe you have passed some invalid value and we can know that without context.
