Steps to reproduce

1. Write a custom JQL, and ensure to add the ID of the data you're filtering such as project per my example below
   • project = 10000
2. Copy the URL with the JQL in it and paste in the web browser (e.g http://localhost:8080/issues/?filter=-3&jql=project%20%3D%2010000)
3. Jira will trigger an error as the example below
   • 

Workaround

• Save the JQL as a filter (http://localhost:8080/issues/?filter=10700)
• Change the IDs to names (e.g http://localhost:8080/issues/?filter=10700&jql=project%20%3D%20%22test%20template%22%20)
