amazon web services - AWS Missing credentials when I try send something to my S3 Bucket (Node.js)

Question

I'm having this issue since yesterday, and I'm having trouble for find a solution.

I'm trying to send somethings to my S3 bucket, but this message appear in my console when I try:

{ [CredentialsError: Missing credentials in config]
  message: 'Missing credentials in config',
  code: 'CredentialsError',
  errno: 'Unknown system errno 64',
  syscall: 'connect',
  time: Thu Oct 09 2014 14:03:56 GMT-0300 (BRT),
  originalError: 
   { message: 'Could not load credentials from any providers',
     code: 'CredentialsError',
     errno: 'Unknown system errno 64',
     syscall: 'connect',
     time: Thu Oct 09 2014 14:03:56 GMT-0300 (BRT),
     originalError: 
      { code: 'Unknown system errno 64',
        errno: 'Unknown system errno 64',
        syscall: 'connect',
        message: 'connect Unknown system errno 64' } } }

And this is my code:

var s3 = new AWS.S3();
AWS.config.loadFromPath('./AwsConfig.json'); 

    s3.putObject(params, function(err) {
        if(err) {
            console.log(err);
        }
        else {
            console.log("Succes");
        }
});

The credentials are correct. Does anyone know what can be? I've searching but I not find anywhere the solution.

My credentials(fake):

{
    "accessKeyId": "BLALBLALBLALLBLALB",
    "secretAccessKey": "BLABLALBLALBLALBLLALBLALLBLALB",
    "region": "sa-east-1",
    "apiVersions": {
      "s3": "2006-03-01",
      "ses": "2010-12-01"
    }
}

EDIT:

For help, all the code:

var fs = require('fs');
var AWS = require('aws-sdk');


var s3 = new AWS.S3();
AWS.config.loadFromPath('./MYPATH.json'); //this is my path to the aws credentials.


var params = {
        Bucket: 'testing-dev-2222',
        Key: file,
        Body: fs.createReadStream(file)
    };

s3.putObject(params, function(err) {
    if(err) {
        console.log(err);
    }
    else {
        console.log("Success");
    }
});

New err:

Error uploading data:  { [PermanentRedirect: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.]

Answer 1

Try hardcoding your params and see if you get the error again :

AWS.config.update({
    accessKeyId: "YOURKEY",
    secretAccessKey: "YOURSECRET",
    "region": "sa-east-1"   <- If you want send something to your bucket, you need take off this settings, because the S3 are global. 
}); // for simplicity. In prod, use loadConfigFromFile, or env variables

var s3 = new AWS.S3();
var params = {
    Bucket: 'makersquest',
    Key: 'mykey.txt',
    Body: "HelloWorld"
};
s3.putObject(params, function (err, res) {
    if (perr) {
        console.log("Error uploading data: ", err);
    } else {
        console.log("Successfully uploaded data to myBucket/myKey");
    }
});
