Hi, sorry for the late response.
There's an OS size limit on arguments passed to spawned processes, and it looks like htmlString
is over the limit. You could still pass the filepath to phantom-test.html:
webshot('file://' + __dirname + '/phantom-test.html', './test.png', function(err) {
if(err) throw err;
console.log('done');
});

Thanks for following up. That makes sense, if you're not using a unix pipe for the htmlString, and i'm not sure that named pipes are yet supported in node's process.child. It's worth noting the max length for htmlString in the docs. I did revert my code to use an http resource. I tried file:// first - and found http:// was more flexible for my situation.
Again, thanks for following up with the explanation.
