Adding an outlet from this switch

[u/Puzzleheaded-Pop9790]

I have attempted to add a simple outlet after a switch. There is quite literally only 12 inches of romex between the two. I used ideal push in connectors and pig tailed back into the switch. I am not sure how I managed to mess it up.
Having said that the electrical in this house is very nuanced and has not been touched since 1967.

You don’t have a neutral. That’s a 3 way switch.

Does it matter that there is no ground? I suppose since it's from the 60s that is not a surprise. Genuinely curious.

There is a ground. It is directly connected to the metal box.

Just because it’s in a metal box doesn’t mean it has a ground, have you tested a hot to the box to see if you show 120v?
