how to display customfield options(dropdown values) if it does not have any context associated

[Tushar Wagh]

customfield_15000 does not have any context associated and I want to display all dropdowns present for the same custom field but as I do not have context id I am not able to use below rest api.

GET /rest/api/3/customField/{fieldId}/context/{contextId}/option

and when tried to get the custom fields options using below link I am getting 405 as method not allowed

/rest/api/latest/customFieldOption?fieldId=customfield_15000

In all honesty, I'd expect it would become permanent and mandatory sooner or later.  How long it will take is really anybody's guess, but when this kind of major interface change has happened in the past, it's usually some with or shortly after the full release of the next major version of Jira (this would be Jira 8 in this case, which is still unannounced, officially)

Anything more than that would be speculation.
