Trouble running cron on Joyent

Question

I'm trying to set up a node script to run as a cron job on Joyent. I can run arbitrary commands but node scripts to seem to execute. As an example:

# cron
# call a script every minute
# being specific about the location of node and the script to run 
* * * * * /home/node/local/nodejs/bin/node /full/path/to/some-script.js

// node script at /full/path/to/some-script.js
var fs = require('fs');
fs.writeFile('/home/node/node-service/some-script.log', new Date.toString(), 'utf8');

What I expect to see after one minute is a file at /home/node/node-service/some-script.log with content like Mon Jan 21 2013 15:19:11 GMT-0600 but I see nothing. This is still the case even if the script is set to full read, write and execute permissions for all users and whether the crontab is set for the root or node users.

What am I missing?

Thanks

It appears to be working now. I'm not sure what I changed that got it working. It may have been a permissions issue.

The fourth optional argument to writeFile is a callback to fire when the file system is done writing the file. You can use it to determine the error that is happening, as it's only argument is an error. Refer to the docs here.
