Unable to use file.replace in SaltStack state

I'm writing a state to change the default SSH port to another value. This is the the .sls file I'm having trouble with:

move port ssh:
  file.replace:
    - path: /etc/ssh/sshd_config
    - pattern: Port 22
    - repl: Port 22222

From the docs it seems the path argument should be supported, but it fails.

# salt-call state.sls common.ssh test=True
local:
----------
          ID: move port ssh
    Function: file.replace
      Result: False
     Comment: Specified file move port ssh is not an absolute path

The following state works, but the way it's written prevents me to do other things.

/etc/ssh/sshd_config:
  file.replace:
    - pattern: Port 22
    - repl: Port 22222
