Error creating json file in node js

Question

I have followed many solutions provided in the previous questions but mine is not working. The problem is in .json extension. Whenever I use filename.json, the app will crash with ERR_CONNECTION_RESET but successfully created an empty .json file. However, if I change the extension to filename.txt, the fs.writeFile will successfully create the filename.txt with the data inside and the app will work as expected. Did I miss any configuration here to create the JSON file? Here is the example code I used.

var jsonData = '{"persons":[{"name":"John","city":"New York"},{"name":"Phil","city":"Ohio"}]}';

// parse json
var jsonObj = JSON.parse(jsonData);
console.log(jsonObj);

// stringify JSON Object
var jsonContent = JSON.stringify(jsonObj);
console.log(jsonContent);

fs.writeFile("./public/output.json", jsonContent, 'utf8', function(err) {
  if (err) {
    console.log("An error occured while writing JSON Object to File.");
    return console.log(err);
  }

  console.log("JSON file has been saved.");
});

So, ERR_CONNECTION_RESET means that the connection was closed midway. My guess, as in the comments, would be that it's a reloading server.

Try using --ignore public/**/*.json and it should work.
