Hi, I see the same problem on a first installation of the solution. Also on a Fujitsu workstation, I don't know if it's a common point, but all our computers are on this manufacturer. Too bad, I really want to use this application.

I have same issue

This seems to be a bug when running Snipe-IT version 5+ as seen here: https://github.com/Scope-IT/marksman/issues/37

I've posted a potential solution at the bottom of that thread.

I haven't been able to get in touch with the developer, so have started my own version of the project. You can download it here if you are interested: https://github.com/ReticentRobot/SnipeAgent

Yes, it has been a long while - but the version I have has the fix in it that I mentioned above.

Cool - out of curiosity how did you wound up fixing it?

Lol, nothing too much - I couldn't remember what it was but found this comment I left back then, this is all I did:

"Disclaimer: I am not a programmer

I've found that if you change line 45 in Category.cs in the SnipeSharp project from:

public bool eula { get; set; }

to

public string eula { get; set; }

that this will get the agent working on 5.x"
