remove all before

Hello, when I run code on remove all before in the firs level, it seems OK but when I check for solution, it returns following error:

`Upon execvpe nodejs [b'nodejs', b'--harmony', b'/opt/project/runners/jsnode.js', b'1db672e4cba4412b97d8f64d977617e6', b'req', b'2323'] in environment id 140621033743232 :Traceback (most recent call last): File "/usr/local/lib/python3.10/site-packages/twisted/internet/process.py", line 398, in fork self.execChild(path, uid, gid, executable, args, environment) File "/usr/local/lib/python3.10/site-packages/twisted/internet/process.py", line 469, in execChild os.execvpe(executable, args, environment) File "/usr/local/lib/python3.10/os.py", line 583, in execvpe _execvpe(file, args, env) File "/usr/local/lib/python3.10/os.py", line 616, in _execvpe raise lastexc File "/usr/local/lib/python3.10/os.py", line 607, in execvpe execfunc(fullname, *argrest) FileNotFoundError: [Errno 2] No such file or directory: b'/usr/bin/nodejs'`

Please, have I done anything wrong?

Thanks,
