How to fix Confluence Workbox issue


The Excellentable v4.2.1.1 or v4.2.1 plugin causes the Confluence workbox to throw an error. The exception mentioned in the stack trace is IllegalArgumentException: Malformed \uxxxx encoding.

Expectation - Excellentable should not cause any cascading failures.


An error message appears instead of notifications in Confluence workbox screen, as shown below:
