I am trying to run an analytic app on Alertyx Server. The app run fine on Designer, but when I try to use the File Browse tool on the server I get the below error message.

I am able to write files from the server so I don't think it is a permissions issue. Based on the file path in the error message it appears as thought it is trying to put the file path of the workflow ahead of the name of the actual file.
Any ideas on what could be causing the problem and how to fix it?
