I have a curl command which i am running in postman, i pass a variable with 2 values and i am using the “Write Responses To File” method to get the output in a json file. However when i run my code in collection runner the 2 value data gets override by the 1 value data. Can someone help me with how to not override the data in the file and keep appending to the existing? Below is the code i have in my tests where its generating the file

// The opts for the server, also includes the data to be written to file

let opts = {

```
requestName: request.name || request.url,

fileExtension: 'json',

mode: 'writeFile', // Change this to any function of the fs library of node to use it.

uniqueIdentifier: 'waddup',

responseData: pm.response.text()

```

};

pm.sendRequest({

```
url: 'http://localhost:3000/write',

method: 'POST',

header: 'Content-Type:application/json',

body: {

    mode: 'raw',

    raw: JSON.stringify(opts)

}

```

}, function (err, res) {

```
console.log(res);

```

});

Hi @sujithkumar.matharas,

Welcome to the Community 👋.

As noted here:  
`mode: 'writeFile', // Change this to any function of the fs library of node to use it.`

You should be able to change this to any function of the fs library of node. Have you tried `appendFile` instead?
