TypeError: Cannot read property 'on' of undefined #1

Hey!

I am getting this error in my application:

........../node_modules/rpi-throttled/lib.js:23 command.stdout.on('data',this.setData.bind(this)); ^

TypeError: Cannot read property 'on' of undefined at RpiThrottled.update (........../node_modules/rpi-throttled/lib.js:23:22)

I have a simple file that calls "update()" function every 5 seconds, indefinitely. After few hours, it crashes with error above. Any idea what I could do? Should I use the synchronous version instead?

Cheers

Apparently the command line process that's executed every time the data is updated couldn't be started for some reason. At any instance, checking every five seconds seems a bit excessive, I'd start with lowering that frequency first. Starting the command line environment, executing the command - all of that may take more than 5 sec.

Thank you for answering. I will increase the time between and see if that fixes it.
