Error 400 on trying to add a contact in mailchimp - node.js

Question

I am getting this error when trying to call the mailchimp API V3 to add a new contact to my list
"type":"http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/","title":"Invalid Resource","status":400,"detail":"The resource submitted could not be validated. For field-specific details, see the \'errors\' array.","instance":"f8b79d9b-1c02-4062-a0e4-847e31f7bd61","errors":[{"field":"","message":"Schema describes object, NULL found instead"}]}'
Here is the code used:
app.post("/", function(req,res){
var email = req.body.email;
var data = {
members : [
{
email_address: email,
status: "subscribed"
}
]
};
var jsonData = JSON.stringify(data);
var options = {
headers :{
'Authorization': 'thomas APIKEY',
'Content-Type': 'application/json',
'Content-Length': jsonData.length
},
url: "https://us20.api.mailchimp.com/3.0/lists",
method: "POST",
data:jsonData
};
console.log(options);
request(options, function(error, response, body){
if(error)
{
console.log(error);
}
else{
console.log(response);
}
})
I tried adding /Listkey/members to my url with no success
Do you have some tips? Thank you

I found the solution, the elements passed to request were not good.
Here is the functional code:
app.post("/", function(req,res){
var email = req.body.email;
var data = {
"email_address": email,
"status" : "subscribed"
};
var options = {
"url": "https://us20.api.mailchimp.com/3.0/lists/c9b9a6e109/members/",
"method": "POST",
"headers": {
"Authorization": "thomas APIKEY"
},
"body": data,
"json": true
};
})
