🔥 The Roast: You're calling getEventMappingsForIntegration with {} but the function signature (calendar.ts:482) still requires integrationId: v.id("calendarIntegrations"). When this runs, args.integrationId will be undefined and ctx.db.get(undefined) will throw. Classic "I changed the comment but not the code" bug.

🩹 The Fix:

Suggested change
const existingMappings = (await ctx.runQuery(calendarInternal.getEventMappingsForIntegration, {})) as Array<{ externalEventId: string; providerEventId: string }>;
const existingMappings = (await ctx.runQuery(calendarInternal.getEventMappingsForIntegration, {
integrationId: integration._id,
})) as Array<{ externalEventId: string; providerEventId: string }>;
