The field 'labels' or 'status' is not supported by the function 'cascadeOption'.

[Andrew van der Bilt]

All custom fields I try to use within advanced search will give above response.

Example JQL Project = O365DO AND issuetype in (Epic, Story) AND labels in cascadeOption("Highlight", none)

Does cascadeOption only work with specific fields?

[Krister Broman _Advania_ · Accepted solution]

the searchfunction of cascadeOption is only possible for the field type 'Cascading Select' not Labels and not Status. A cascade select will have a tier 1 and a tier 2 value. Tier 2 will have different values based on what value is selected in Tier 1. 

If you need to search for issues that have either "Highlight" or is blank then use a nested search query

project = O365DO AND ( labels in (Highlight, Lowlight, etc) OR labels IS EMPTY)

Look in the guide for more info on the advanced search options: https://confluence.atlassian.com/jiracorecloud/advanced-searching-functions-reference-765593719.html#Advancedsearching-functionsreference-cascadeOptioncascadeOption()

Thanks for your reply. 

Too bad, because I need to have a results of Epics with a certain label and their child stories. Looks like that is not possible in cloud Jira JQL.

Nope you need Scriptrunner to get that working in cloud: http://scriptrunner-docs.connect.adaptavist.com/jiracloud/enhanced-search.html#_epicsof
