Viewing errors and sourcemaps

You can view all errors sent to LaunchDarkly under Errors in the LaunchDarkly user interface. To learn more, read Error monitoring.

When you use the Errors page in LaunchDarkly to help debug an error, it’s helpful to have a stack trace from the original file in your codebase to help understand what is going wrong. To provide this, LaunchDarkly needs access to the sourcemaps from your codebase. You can send your sourcemaps to LaunchDarkly using the ldcli sourcemaps upload command in the LaunchDarkly CLI. To learn how, read Use ldcli for uploading sourcemaps.
