Expected 0 arguments, got n

[oianson]

On Robot Framework 7.0 when trying to use 'Debug' keyword and calling the following python keyword, I am getting an error saying expected 0 arguments, got 2.
I get the error regardless of how many arguments the keyword takes

    @keyword('attach module "${module:[^"]+}" console and execute "${command:[^"]+}"')
    def attach_console_and_execute(self, module, command):

attach module "100" console and execute "show version"
! Expression: attach module "100" console and execute "show version"
! Execution error: Keyword 'CXTA.robot.DeviceCli.attach module "${module:[^"]+}" console and execute "${command:[^"]+}"' expected 0 arguments, got 2.

Do not observe the same behaviour if using normal arguments

I can reproduce this with a simple setup:

*** Settings ***
Library   workspace.lib
Library   RobotDebug

*** Test Cases ***
test
    keyword "arg"
    Debug
    keyword "arg"

workspace/lib.py:

from robot.api.deco import keyword

class lib:
    @keyword('keyword "${arg}"')
    def keyword(self, arg):
        """
        This is a keyword that takes an argument and prints it.
        """
        print(f"Keyword called with argument: {arg}")

Console output:
