This error should not be encountered under normal uses of our products as it offers no API to reproduce it manually.
In the code, this error mainly exists to check for missing request tokens in the server cache or to prevent object casting issues in the code. As such, there is no reproduction procedure for this error.
Atlassian document this issue as possible with applications that allows OAuth tokens to be manually revoked. In such cases, this error might appear in the log files but the user should be prompted with the login page instead of an error.
