Jira Cloud C# SDK 12.0.0.0 Throw error after looping through certain issues

Hi,

I am using Jira sdk 12.0.0.0 via C# to connect to Jira Cloud.

I am able to loop through the jira issues but at certain jira issues it breaks

My code as below

var jiraObj = Atlassian.Jira.Jira.CreateRestClient("jiracloudurl", "username", "Apitoken", new JiraRestClientSettings());
 IPagedQueryResult<Issue> jqlResults= await jiraObj.Issues.GetIssuesFromJqlAsync(options);
foreach (Issue issue in jqlResults)
                {
                    try
                    {
                        Console.WriteLine(Convert.ToString(issue.Key));
                    }
                    catch (Exception ex)
                    {
                        Console.WriteLine(ex.ToString());
                    }
}

Can anyone advise whats the issue.

@SuperScrummer - not super familiar with that .NET SDK, but… I did notice this:

https://bitbucket.org/farmas/atlassian.net-sdk/commits/

There’s a new version (12.1.0) that has commits related to custom field deserialization issues. Perhaps try upgrading to that latest version on NuGet.
