jirarestapi在创建问题时出错

hi我在试图使用rest api和php在jira中创建问题时遇到以下错误。创建问题时出错：对象（stdClass）[1]public"errorMessages"=>数组（大小=0）空的公共"错误"=>对象（stdClass）[2]public"summary"=>无法设置string"字段"summary"。是的不在合适的屏幕上，或者未知（长度=79）public"description"=>string"字段"description"不能为设置它不在合适的屏幕上，或者未知（长度=83）`我正在使用以下源代码：

<?php
 define('JIRA_URL', 'xxxxxxxx');
 define('USERNAME', 'xxxxxxxxx');
 define('PASSWORD', 'xxxxxxxx');
 function post_to($resource, $data) {
 $curlname=CURLOPT_POST;
 $curlvalue=1;  
 $jdata = json_encode($data);
 $ch = curl_init();
 curl_setopt_array($ch, array(
    $curlname => $curlvalue,
    CURLOPT_URL => JIRA_URL . '/rest/api/latest/' . $resource,
    CURLOPT_USERPWD => USERNAME . ':' . PASSWORD,
    CURLOPT_POSTFIELDS => $jdata,
    CURLOPT_HTTPHEADER => array('Content-type: application/json'),
    CURLOPT_RETURNTRANSFER => true
 ));
 $result = curl_exec($ch);
 curl_close($ch);
 return json_decode($result);
 }
 function create_issue($issue) {
 return post_to('issue', $issue);
 }
 $new_issue = array(
 'fields' => array(
    'project' => array('key' => 'xxx'),
    'summary' => 'Test via REST',
    'description' => 'Description of issue goes here.',
    'issuetype' => array('name' => 'Task')
 )
 );
 $result = create_issue($new_issue);
 if (property_exists($result, 'errors')) {
 echo "Error(s) creating issue:'n";
 var_dump($result);
  } else {
 echo "New issue created at " . JIRA_URL ."/browse/{$result->key}'n";
 }
 ?>

出于安全原因，带有xxxx的字段被替换。我想知道如何纠正这个错误。
