Magento 2.2 REST API Error with ‘@param string[] $types’ – Fix

Using magento 2.2. I create rest api for edit address which need pass param in 'array of string' but i get an error:

Doc: Magento Configure services as web APIs

Used array of string for pass param

"street": ["new, wat phnom, phnom penh"]

Message

"message": "Error occurred during \"street\" processing. Invalid type for value: \"array\". Expected Type: \"string\".",

My JSON

{
"address":{
"addressId":85,
"street": ["new, wat phnom, phnom penh"],
"latitude":"11.33333664",
"longitude":"104.99778855"
}
}

Interface

<?php
namespace Iota\EShopping\Model\Address;

class Address
 {
private $addressId;
private $street;


/**
 * addressId
 * @return int
 */
public function getAddressId(){
    return $this->addressId;
}

/**
 * addressId
 * @param int $addressId
 * @return Address
 */
public function setAddressId($addressId){
    $this->addressId = $addressId;
    return $this;
}


/**
 * street
 * @return string
 */
public function getStreet(){
    return $this->street;
}

/**
 * street
 * @param string[] $street
 * @return Address
 */
public function setStreet($street){
    $this->street = $street;
    return $this;
}
}
