GitHub Actions Azure SSH

I'm trying to SSH into a Azure VM. While trying to SSH, in the actions log, it seems to print "***" (i assume that it is hiding the private key for SSH) but when I do cat ~/.ssh/id_rsa it shows nothing. Why is this?

​

Secret exists

\"Context access might be invalid\" but I'm sure it exists. Not shown is `ssh -i ~/.ssh/id_rsa name@ipaddress\" which I have confirmed to work on a docker instance and other computer.

​

nothing. why??
