Error when uploading files from a directory....

I don't remember how this is supposed to work, but it seems that when I upload files from the "upload" directory, we get the error below. In general we want people to be able to upload photos without getting an error like this.

My file
file.path
UnkonwnElizaSpring.JPG
file.path
Error: child failed: path argument was an invalid path = "/apps/abc/tags/uploads/UnkonwnElizaSpring.JPG". Paths must be non-empty strings and can't contain ".", "#", "$", "[", or "]"

Start in server.js at writeTagIntoDB around line 114, then follow the upload flow around line 204. Reproduce the failure by uploading a photo from the upload directory and inspect the Firebase path value shown in the error. Done means the upload completes without the invalid-path error.
