Hi @david.pinn
Thanks for the suggestion , What I did is first I called this rest call
https://developer.atlassian.com/cloud/jira/platform/rest/v3/?utm_source=%2Fcloud%2Fjira%2Fplatform%2Frest%2F&utm_medium=302#api-rest-api-3-field-post
for creating the custom fields in Jira. After that, I am trying to add options using the rest call then also the same error. Anything wrong in this way.
Can You please suggest some way to do that properly?
