客户端需要访问服务器端之一，客户端会收到以下错误：
<?php
include_once"dbconfig.php";
$name = "aaa";
$email = "a@a.a";
$phone = "666";
$mysqli = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_DATABASE);
if ($mysqli->connect_error) {
die('Error : ('. $mysqli->connect_errno .') '. $mysqli->connect_error);
}
$sql = "SELECT id, name, email,phone FROM `clients` WHERE `email` = '". $email."' AND `phone` = ". $phone;
$stmt = $mysqli->prepare($sql);
$stmt->execute();
$stmt->bind_result($id, $name, $email, $phone);
$stmt->store_result();
if( $stmt->num_rows > 0 ) {
echo "This Email already is in system";
}else{
$stmt = $mysqli->prepare("INSERT INTO clients (`name`,`email`,`phone`) VALUES (?, ?, ?)");
$stmt->bind_param("sss", $email, $phone, $name);
$stmt->execute();
echo "New records created successfully";
}
$stmt->close();
$mysqli->close();
?>
错误发生在gov.samhsa.c2s.phr.service.IExHubDataServiceImpl.getPatientData（IExHubDataServiceImpl.java），代码为：

其中，PatientDataResponse.class是
final ResponseEntity<PatientDataResponse> pdrEntitiy = restTemplate.exchange(iexHubUrl, HttpMethod.GET, reqEntity, PatientDataResponse.class);
服务器端的日志如下：
@JsonIgnoreProperties(ignoreUnknown = true)
public class PatientDataResponse implements Serializable {
@JsonProperty("Documents")
private List<Document> documents;
public List<Document> getDocuments() {
return documents;
}
public void setDocuments(List<Document> documents) {
this.documents = documents;
}
}
根据服务器日志，许多地方都说这个错误是由于maven dependecies不一致，但在我的情况下没有意义。相关的maven依赖关系如下：

你能帮我弄清楚我的错误的根本原因是什么吗？
