ssh permission denied when prefixing with ssh protocol

Question

I try to add a ssh key to my GitLab account in order to use it through npm.

I added my key following https://docs.gitlab.com/ee/ssh/.

ssh -T [email protected]

Is working fine and deliver the message Welcome to Gitlab, username.

But ssh -T ssh://[email protected] is not working and give me this error message:

Permission denied (publickey).

And when I run npm install on my node project where I added my node module as a dependency inside the package.json file, it's returning the following error:

npm ERR! Error while executing:
npm ERR! /usr/bin/git ls-remote -h -t ssh://[email protected]/myproject/myproject.git
npm ERR!
npm ERR! Permission denied (publickey).
npm ERR! fatal: Could not read from remote repository.
npm ERR!
npm ERR! Please make sure you have the correct access rights
npm ERR! and the repository exists.
npm ERR!
npm ERR! exited with error code: 128

I added my dependency inside package.json as follow:

"my-project": "[email protected]:myproject/myproject.git",

I'm not comfortable with ssh and key pairing, if anyone could tell me what is wrong with my configuration it will help me a lot, thanks.

It's kind of funny to be misled by the following line (talking about myself):

ssh -T ssh://[email protected]

The command doesn't expect actually a protocol prefix, but a hostname prefixed or not by a user name followed by an arobase, as said the manual page:

ssh [-1246AaCfGgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec] [-D [bind_address:]port] [-E log_file] [-e escape_char] [-F configfile] [-I pkcs11] [-i identity_file] [-J [user@]host[:port]] [-L address] [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port] [-Q query_option] [-R address] [-S ctl_path] [-W host:port] [-w local_tun[:remote_tun]] [user@]hostname [command]

Here, it takes actually ssh://git as a user name. That's why it won't log in since the user name which whom you connect has to be git, and not ssh://git.
