Default Trying to obtaining the surface forces

Hi,

I'm trying to obtain the output of forces (normal and tangential) for the whole surface of the object around which the flow occurs. I added this to functions in controlDict:

Code:
forces
    {
        type            forces;
        libs            ("libforces.so");
        patches
        (
            wall_001
        );
		CofR            (0 0 0);
		
		rho            rhoInf;

		log            true;

		rhoInf            1;

    }
The analysis finished successfully and I can open the results in ParaView but there are no variables associated with forces and I've noticed a long output with repeating errors:

Code:
File "...\CfdConsoleProcess.py", line 98, in readStdout
new_text = self.stdoutHook(text)
File "...\Solve\TaskPanelCfdSolverControl.py", line 290, in gotOutputLines
self.solver_runner.process_output(lines)
File "...\Solve\CfdRunnableFoam.py", line 263, in process_output
f = self.forces[self.in_forces_section]
KeyError: 'forces'
Do you know what can be wrong here? Do I need to include some additional libraries?
