Magento – Magento 2 : Customer creation failed using customer API

I am trying to create customer using API in magento 2.2.3.

Below api is working well and customer can created successfully but issue only arrive while adding address.

If i send address field with customer magento show me error like below.

Here is the data i am sending to api

Array
(
    [customer] => Array
        (
            [website_id] => 1
            [store_id] => 1
            [group_id] => 1
            [firstname] => name
            [lastname] => lastname
            [custom_attributes] => Array
                (
                    [customer_code] => 3654256542156954
                )

            [email] => example@gmail.com
            [addresses] => Array
                (
                    [region] => 67
                    [country_id] => CA
                    [countryId] => CA
                    [street] => 3652 Rohnstand Road  
                    [firstname] => name
                    [lastname] => lastname
                    [company] => 3654256542156954
                    [telephone] => 999-999-9999
                    [city] => city
                    [postcode] => pincode
                )

        )

    [password] => password
)

This is how api calling.

    $data = $this->mapData($data);
    $ch = curl_init("http://127.0.0.1/project/index.php/rest/V1/customers");
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Authorization: Bearer " . json_decode($this->_token)));

    $result = curl_exec($ch);
