The code attempts to deserialize the json response, giving a null reference exception

[Ravesh Kumar]

Hi ,

I am fetching (story or sub-task) data from JIRA SDK with following nuget package 

<package id="Atlassian.SDK" version="12.1.0" targetFramework="net46" />
<package id="Newtonsoft.Json" version="10.0.3" targetFramework="net46" />
<package id="RestSharp" version="106.10.1" targetFramework="net46" /> 

I used below function to fetch the result 

IPagedQueryResult<Issue> result = await jira.Issues.GetIssuesFromJqlAsync("project = 'CREDRE' AND issuetype='Story' and updatedDate>= -4d ORDER BY id DESC", int.MaxValue);

but some some story or task it return an error giving a null reference exception.

Please see attached screens of exact issue while fetching (story or sub-task) from JIRA API.

You can bypass this problem if you enable UserPrivacyMode on the JiraClient level

---

// To be able to handle User Picker (multiple users) field type properly
jiraClient.RestClient.Settings.EnableUserPrivacyMode = true;

Facing same issue. Any resolution?

Atlassian.SDK 13 the same problem.

Always null reference exception after reading result after GetIssuesFromJqlAsync

Needs a simple null check in MultiObjectCustomFieldValueSerializer. For personal use, I decompiled and added a single '?' to make it work. The project seems abandoned though since 2022...
