Cause
This error indicates that there is a CORS related error caused by broken applinks in your Jira environment. Further investigation will reveal that you encounter additional errors while navigating to Settings > Application > Application Links in Jira.
Solution
To fix this, you will need to perform a database query to determine the appropriate applink identifiers, then delete the applink using Jira's API
⚠️ The queries below may not run on your database due to syntax, formatting, or something else. Please consult with your DBA to ensure that the same data, from the same tables, can be queried on your Jira Environment.
Query 1:
This query pulls the RPC URLs for the AppLinks that are currently configured in Jira. You will need the ID value for your API call and can use the subsequent columns as a reference

ON
propertyentry.id = propertystring.id
WHERE
property_key LIKE 'applinks%rpc.url';Query 2:
This query lists out similar applinks on your Jira environment but the property_key is formatted differently than the other query. You will need the ID value for your API call and can use the subsequent columns as a reference

where a.property_key like 'applinks%name';API Call
ℹ️ Please ensure that you are using a Personal Access Token when making API calls to Jira. See: Personal Access Tokens in Jira for additional steps to generate a token.
For each ID returned, you will need to delete the associated applink from Jira using the applink API endpoint. You may refer to the example below for reference:

curl -X DELETE -H "Authorization: Bearer $token" -H "Accept: application/json" https://$jira_url/rest/applinks/1.0/applicationlink/$appLinkId;Was this helpful?
