response.statusText=“OK” but falls into error callback from ajax with jQuery

    $_SESSION[\'accountId\'] = $accountId;
    $_SESSION[\'type\'] = $_POST[\'accountType\'];
    echo \'1\';
    return;

There are more useful parameters to the error callback. Try getting the textStatus.

error: function(XHR, textStatus, errorThrown) { console.log(textStatus); } 

Check what that is.

A quick guess is that you meant to use dataType: 'text' not 'text/plain'. (Check documentation)

$.ajax({
    type:'POST',
    data: $("#flowFormSubmit").serialize(),
    dataType:'text',
    timeout:1000,
    success:function(response){
        if(-1 == response)
                alert('fail');
        else
                alert('succeed');
    }
});
