Cognos Analytics degradation

Incident Report for Brown University

Monitoring

A recent Google Chrome update (version 150.x) has introduced a compatibility issue with Cognos Analytics.

Impacted Scenarios in Chrome:

Running Reports—When running a report interactively and using the output toolbar to re-run the report or change format (e.g., clicking "Run" or "Select a format" then PDF, Excel, HTML), an error may occur. You can close the report and re-run it in your desired format or use Firefox as a temporary workaround.

Authoring Reports—Creating or modifying reports will result in an error. Use Firefox as a temporary workaround.

NOTE: Users may experience the same errors in Edge since it also uses the Chromium codebase.
