Operation value must be an Atlassian Document (see the Atlassian Document Format) error message

[Elif Alverson]

Hello, 

I am getting below error message while I am trying to create a Jira ticket with slack/workflow/shortcut by using workflows by jira app. I have a few more custom fields for this workflow. I am only getting this message when I did not fill these two custom fields; when I fill them , no errors.

Any ideas? Any help will be appreciated. Please see these two Custom fields below.

Error: Jira encounted an error while attempting to create the issue: {"customfield_10207":"Operation value must be an Atlassian Document (see the Atlassian Document Format)","customfield_10206":"Operation value must be an Atlassian Document (see the Atlassian Document Format)"}
