list_error_groups

List the project's fingerprinted application-error groups.

List the project's application-error groups — the fingerprinted, deduplicated exceptions your telemetry agent reports (the Dashboard's Telemetry → Errors drilldown). Each group collapses identical errors (by exception type + normalized stack) into one row with an occurrence count, level, first/last-seen times, the latest stack + URL, and any linked GitHub issue.
