Cli works, node version gives error

[nick-lehmann]

I try to print out large responses from an API pretty to the console. When using console.log(prettyjson.render(body)) I will get the normal output. When I save the response to a file and invoke the CLI version onto it, it works very fine (great job, still big thanks to you!).

I have decided to only save a smaller part of it and try it out, just to make sure it is not because of the size of the string. I have also linted it, but the JSON is valid. The excerpt is

When using the following code, I get the error message displayed underneath

var prettyjson = require('prettyjson'),
    fs = require('fs');

var data = fs.readFile('todoistResponse');

var options = {
    noColors: true,
};

console.log(prettyjson.render(data, options));

I would be delighted to hear any advise!
