Warning error for writing a file into a directory

I am getting the below warning error while writing a file into a directory. I haven’t had this issue before as this process was developed 2 months before. I have masked the Org name for security purpose in the screenshot.

DataAcquisition is the project space under the Org and DEV_Micros is the project folder.

The file is actually getting written into the specified project folder. But i still get this warning message, when I analyze the snaps in the dashboard.

Not sure if this is anything to do with latest Snaplogic release.
