how to display customfield options(dropdown values) in jira on prem server using rest api ?

[Tushar Wagh]

Document https://docs.atlassian.com/software/jira/docs/api/REST/9.7.0/

I am using below API from above document (Get custom field options) and it is giving me 404 not found error.

GET /rest/api/2/customFields/{customFieldId}/options

Error:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<status>

<status-code>404</status-code>

<message>null for uri: https://test.test.com//rest/api/2/customFields/customfield_15000/options</message>
