Failing to set Insight field when creating Bug issue via REST API

Question

I am working on creation of Bug issues via REST API but I am having trouble setting the value of an Insight field. Basically I am doing exactly what is described under "Create Issue" on
https://confluence.atlassian.com/insightapps/insight-with-jira-rest-api-1085180905.html

I am able to update the Insight field doing what is described under "Update Issue" in the same article.

I do not receive any error messages when I create, and the Bug does get created, it is just that the Insight field does not get populated. Any ideas?

Yes, Data Center. Version of Jira Service Management is 4.20.11.

Ok and can you share the version of your Jira Service Management? I guess you are on Data Center, right?

Currently experimenting from Postman.

Endpoint: rest/api/2/issue/

Method: POST

JSON:

{    "fields": {        "project": {            "key": "DBSQA"        },        "issuetype": {            "name": "Bug"        },        "summary": "Created via Jira REST API",        "description": "Some description.",        "customfield_11617": [{"key": "DB-115"}]    }}

Authentication is the same regardless if I create or update. I have tried both basic authentication using my user/password and bearer token using API key. No errors reported either way.
