"Invalid Directory" response to file choose component

I have a file chooser component in a form we use for checking files into our repository.

I am attempting to add a new repository and have everything completed as per documentation I made on this process a while back, but after selecting the repository staging location and then clicking on the button to select the file to check in (the file chooser component), the return is '

Invalid directory: "/kintana/prod/VC/STAGING/Workday"

Has anyone seen this before?  And if so, what attempts were made to resolve it?

 

Thanks,

Steve
