Jira Rest version: 2
I am trying to add about 100,000 options spread across 3 levels to our MLCS custom field. I have tried using the bulk upload and it fails (Jira goes down with error 502) when the csv has about 10k rows or more. I have therefore been forced to try to use the Jira API to add those options.
I have looked at this response https://community.atlassian.com/t5/Answers-Developer-Questions/How-to-update-a-MLCS-custom-field-through-REST/qaq-p/471849 and I'm trying to understand how to format that request.
1. What endpoint is this request being made to? From the documentation I can't see a customField request that takes a request body of that nature.
2. From the logs attached in that question, I can see the request is (maybe) being made to /rest/api/latest/issue/. Is that correct? I am trying to update the field options for all issues, not one specific issue.
Given the custom field id customfield_12345, I will appreciate an example of how to add 3 levels of options to the field using the rest API.
