Whenever a job fails, Swift will attempt to transfer the stdout and
stderr of that job. There is no guarantee that those files are created
by the job (i.e. they only get created when at least one character is
written to them). Hence the transfer of these may fail. It is not an
error at the Swift level. Again, it's a pattern of the following kind:

try {
  optionalOperationWhichDoesNotHaveToSucceed();
}
catch (Exception e) {
  log(e);
}
