I’ve ran into this as well. It seems to occur shortly after adding a new device and before the device is polled/discovered. Attached is a screenshot of the error message. Everything is fine after the device is discovered/polled.

You've omitted basically all of the relevant information.

When asking for help, include screenshots of things not working including proof of URL and the like.

Otherwise people will just assume you're confused and probably ignore you, since that's easier than going digging for information.

Nothing is more annoying than having to question someone to help them because they don't bother giving you any actual information.

"I clicked a link and it doesn't work, any idea why?"

Oddly enough, no.

First time I've run into this issue...

I added a device.  It shows up fine in the device hitlist.  But when I 
click on the device name for details I get:

"No valid device specified
A valid device was not specified in the URL. Please retype and try again."


Any idea why this would be occurring?  No way to delete/readd the device 
too because of this.  Any help appreciated!
