Getting the following from a popup form I create that contains a File Upload. It appears that your allowed to use a “/” character in the identifier of the popup (I was using the path to the view) but if you do that, it messes with route handling…

```auto
HTTP ERROR 404 No route match for path: /upload-file/PE/3ed75713/Pplm/ul/form.0:6:2
URI:	/data/perspective/upload-file/PE/3ed75713/Pplm/ul/form.0:6:2
STATUS:	404
MESSAGE:	No route match for path: /upload-file/PE/3ed75713/Pplm/ul/form.0:6:2
SERVLET:	DataRoutes

```

Perhaps the identifier should not allow certain url characters? Or in the backend Ignition should sanitize the designer input…
