The saved Goal + Funnel reports used a pre-v3.1.0 parameters shape (urls/dateRange)
that umami 3.1.0's report schema rejects (400 -> 'Something went wrong'). Migrated
both reports in the umami DB to the current funnelReportSchema/goalReportSchema
(steps[], top-level dates, goal type/value). Verified funnel route now passes schema
validation. TODO updated/closed.
