jql - unable to extract description field

[Omair Ahmed]

Hello, Given the query parameters below, I want to get the description field. However, the query is not returning anything. I don't understand why.

$ curl -D- -u username:password -o issues.json -X GET "https://jira.company.com/rest/api/2/search?jql=project=MyProject+AND+issuetype=Story+AND+Status=Open+AND+description is not EMPTY"

After some experimentation, I came up with this:

curl -D- -u username:password -o issues.json -X GET "https://jira.company/rest/api/2/search?jql=project=MyProject+AND+issuetype=Story+AND+Status=Open+AND+Description:~'TRUE'"

which produces the output, which is confusing because the field exists and I can read it just fine via the JIRA web interface.

{"errorMessages":["Field 'Description:' does not exist or you do not have permission to view it."],"errors":{}}
