Steps to reproduce:
- Create a new project and use IN as the project key.
- Go to https://<instance name>/projects/IN/issues
(This example we use IN, there are a list of reserved words on the comment below)
- JIRA should display issues of IN project
- JIRA doesn't display any issues
Checking from the network request /rest/issueNav/1/issueTable, it returns 404 Bad Request with the below response:
NOTE: it only affects the Project Navigation's issue panel, reverting to the old project view will workaround this issue at the mean time.
Change the Project Key of your project. Make sure it avoids one of the Reserved JQL words (see this comment below).
