无法在Amazon EC2实例上运行Node.js child_process

Question

I am running nodejs child_process function spawn() to do mongoexport. I have passed all the necessary fields to the command and it is working fine on my local machine. Below is the function code

userDetailsChild = spawn('mongoexport', ['--username',username,'--
password',password,'--db',db,'--collection','users','--type', 'csv', 
'--fields', 'userId,firstName','--
out','/home/bitnami/apps/webapp/dist/server/prod/public/user-
details.csv']);

userDetailsChild.on('exit', function (code: any) {
  if (code != 0) {
    userDetailsChild.kill();
    callback(new Error(), null);
  } else {
    console.log('userDetailsChild process closed with code ' + code);
    userDetailsChild.kill();
  }
});

When I try to run the same code with server credentials on amazon WordPress ec2 instance on my server machine it fails with no error message. Somewhere I have seen path variables set as process.env['PATH'] = process.env['PATH'] + ':' + process.env['LAMBDA_TASK_ROOT']; But didnt worked in my case. Any help will be appreciated!!

While I do not know why the command is failing, I do know that you appear to be ignoring the more than likely helpful information coming back to you via stderr. ;)
