🐛 Bug Detection

Potential issues found in the following files:

• browser_use/agent/service.py

The error message:
TypeError: TestRegistry.test_execute_action_with_and_without_browser_context..test_action_with_browser() missing 1 required positional argument: 'browser'
indicates that when executing the action “test_action_with_browser” via Registry.execute_action, the browser parameter is not being passed as expected. In our test, we explicitly call execute_action with an extra keyword argument (browser=mock_browser). However, during the call to the target function (via something like “await action.function(**validated_params.model_dump(), **extra_args)”), the value for “browser” is missing, resulting in a TypeError. This implies that there is an issue in the code of the registry’s execute_action method (or in how it merges parameters) so that the extra arguments are not forwarded correctly to functions requiring the browser parameter.

Thus, the error is caused by a bug in the code being tested.
