Cannot put object to Amazon S3 bucket - amazon-s3

Question

I'm fighting with it for the last couple of days and I'm hopeless.
I use Zend S3 lib to access my S3 via IAM account.
I'm able to list and create my buckets, but I cannot put any object nor read info ($s3->getInfo()) of a sample file I uploaded via console.
I set to my IAM account to full access: AmazonS3FullAccess, also added my own:
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "VisualEditor0",
"Effect": "Allow",
"Action": [
"s3:GetAccessPoint",
"s3:PutAccountPublicAccessBlock",
"s3:GetAccountPublicAccessBlock",
"s3:ListAllMyBuckets",
"s3:ListAccessPoints",
"s3:ListJobs",
"s3:CreateJob",
"s3:HeadBucket"
],
"Resource": "*"
},
{
"Sid": "VisualEditor1",
"Effect": "Allow",
"Action": "s3:*",
"Resource": [
"arn:aws:s3:::*",
"arn:aws:s3:*:*:accesspoint/*",
"arn:aws:s3:*:*:job/*"
]
},
{
"Sid": "VisualEditor2",
"Effect": "Allow",
"Action": "s3:*",
"Resource": "arn:aws:s3:::*/*"
}
]
}
This is my PHP code:
$amazonKey = AWS_ACCESS_KEY;
$amazonSecret = AWS_SECRET_ACCESS_KEY;
$s3 = new Zend_Service_Amazon_S3($amazonKey, $amazonSecret);
//Avaliable buckets this code works:
$this->view->content.="-----------Avaliable buckets:-------------<br>";
foreach($s3->getBuckets() as $bucket)
$this->view->content.=$bucket."<br>";
//this doesn't work
$amazonBucket='map-markers';
$object=$amazonBucket."/myobject";
$result=$s3->putObject($object, "somedata");
if ($result===false) $this->view->content.="putObject: '.$object.' FAIL!";
else
$this->view->content.="putObject: ".print_r($result)."<br>";
Also I tried C++ builder lib for AWS TAmazonStorageService: `
if (s3->UploadObject(BUCKET_NAME,OBJ_NAME,AnsiString("test").BytesOf()),true,0, amzbaPrivate, amzrNotSpecified, ResponseInfo) {
TVarRec args[1] = {ResponseInfo->StatusMessage};
Console("UploadObject:Upload to "+AnsiString(BUCKET_NAME)+" "+OBJ_NAME+" OK!");
}
else
{
TVarRec args[1] = {ResponseInfo->StatusMessage};
Console(Format(AnsiString("UploadObject Failure! %s"), args, 0));
}
S3->UploadObject returns true along with "HTTP 200" in ResponseInfo but the object is not created.
Bucket permissions are like this :
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "S3Permissions",
"Effect": "Allow",
"Principal": "*",
"Action": "s3:*",
"Resource": [
"arn:aws:s3:::map-markers/*",
"arn:aws:s3:::map-markers"
]
}
]
}
Additionally I unblocked all public access to the bucket.
I have no Idea what else could I do?
best regards
Tom
