Warning - Use of this tool exposes you to potential security threats.

Hi, I've been trying to do some SPFx development and I have now started seeing the following error in my developer tools pane: 

It seems a little concerning at least, can anyone advise on why it's happening?

Thanks...

Ok so, I should have googled better before I got worried. Apparently it's expected.

Would still be interested to know why it happens all the same.

Hi @John Condron

Yes, that's an expected warning from the framework. Just ignore it and carry on :)
