How to prevent getting error messages in html format for jira rest APIs

Naman Goenka

Scenario: Jira rest get api call to fetch an issue using wrong credentials in expected to give a 401 error.  

curl --location --request GET 'https://{jira_instance_name}/rest/api/2/issue/11662' \

--header 'X-Atlassian-Token: no-check' \

--header 'Accept: application/json' \

--header 'Authorization: Basic {token}'

But I want to get the error response in json format instead of long weird html error like

<html>

<head>

<title>Unauthorized (401)</title>

<!--[if IE]><![endif]-->

<script type="text/javascript">

(function() {

var contextPath = '';.......

Jira Server: 8.20.18

Steps tried: 

1. Using X-Atlassian-Token: no-check
2. Using Accept: application/json' 
3. Updated the jira.webapi.enableJsonErrorResponse property to true in the jira-config.properties file and restarted Jira

In the jira-config.properties file, try setting the jira.toothFairy.grantAllMyWishes property to true and see if that works.
