Output only certain fields in Jira

[Max Mustermann]

Hello,
I only want to output certain fields in Jira. At the moment all fields are output (because of the *all).

For example, if I want to output the id field, then the RestClientException occurs.

Where, in Jira, are the available fields displayed?

System.out.println(restClient.getSearchClient().searchJql(
"project = \"<project>\" AND status = \"open\"" ,
2,
1,
Sets.newHashSet("*all")).
claim());
