I guess which does not return an error code. If it does not find

So the change of code did not help, because there is just no error message.
Could there be a $path problem in the subprocess started inside the binary?
You're confusing the error code (an integer returned from _every_ exiting
process) and the process' stdout and stderr, which are data streams.
This is why I suggested the check_returncode() method, which examines the error
code.
