Hi @drkbllo,

Could you share a way to reproduce the error you are getting?

Also: please remember that this is open source, developed on my spare time and that no one owes you a timely answer on a Github issue. Your previous comment feels really off. That and the fact you opened a one line issue without any greetings and any way to reproduce the issue.

Best regards.

No worries.

Now, do you have a way to reproduce this?
Can you send the full output of the tool?
Right now I have no way of knowing what goes wrong.
We don't call struct directly so this must be in one of our dependencies.
