Does Fullstory capture uncaught exceptions?

Yes! Fullstory captures uncaught exceptions so you can identify sessions where errors are impacting your digital experience using Dev Tools, Search, Metrics and Dashboards. This helps you understand how many users were impacted and how urgent it is to prioritize a fix. 

In order to search for uncaught exceptions, Console Data Capture must be enabled. Console Data Capture is enabled by default, however, if it has been disabled, you will not be able to search for uncaught exceptions until it is enabled again. 

To identify uncaught exceptions, create a search using the "Uncaught exceptions" event filter.

To get more specific, refine your search using the "Web source file URL" dependent criteria for web or the "Mobile Source file" criteria for mobile.

Your search results will return a list of sessions impacted by uncaught exceptions. Watch a session and use Dev Tools to find and debug errors.

You can also track the impact of uncaught exceptions using metrics and dashboards. For example, these dimensionality cards show top uncaught exceptions by text and source file URL.
