An unknown error occured in OnBase Studio 16. How do I stop this error?

[John_Marshall]

It's been happening whenever I try to open some of the C# unity scripts. I think the IDE is trying to do some frivolous lookup in the background that fails and creates the popup. 

Restarting Studio doesn't work.

Here's the stacktrace: System.Reflection.TargetInvocationException
Exception has been thrown by the target of an invocation.

Hello John,
First, thank you for posting your question to Community.

This behavior has been identified and addressed via SCR 251149. It has to do with the User Groups assigned to the Unity script. One or more of them no longer exists in OnBase (possibly deleted by an administrator), and so when the script is loading and it attempts to check the User Groups, the error occurs. This behavior has been corrected in all builds of OnBase 17.

Normally, I would recommend contacting your first line of support to have the specifics of your issue reviewed so that, if appropriate, you can be added to the SCR, but I know you've already done that and we've taken care of the rest. Thank you for your follow through, and, again, thank you for allowing us to address your concern.
