Default conferencing app '${defaultApp.appSlug}' doesnt exis

Error message

Default conferencing app '${defaultApp.appSlug}' doesnt exist.

What it means

Thrown by bulkUpdateTeamEventsToDefaultLocation when the team's defaultConferencingApp.appSlug does not resolve to a valid app with a location type via getAppFromSlug. Team-level counterpart of the user version: the stored team default refers to an app that no longer exists or lacks a conferencing location.

Solutions

Have a team admin re-select a current default conferencing app in team settings.
Migrate team metadata slugs if an app was renamed in an upgrade.
Ensure the target app is installed/generated so getAppFromSlug resolves it.
Guard callers and prompt re-selection when the slug is invalid.

Example fix

// before
await bulkUpdateTeamEventsToDefaultLocation({ eventTypeIds, teamId, prisma });
// after
const slug = parsed.data?.defaultConferencingApp?.appSlug;
if (!slug || !getAppFromSlug(slug)?.appData?.location?.type) {
  return res.status(400).json({ message: 'Team default conferencing app unavailable' });
}

Defensive patterns

Strategy: validation

Validate before calling

import { getAppFromSlug } from '@calcom/app-store/utils';
const slug = parsed.data?.defaultConferencingApp?.appSlug;
if (!slug || !getAppFromSlug(slug)?.appData?.location?.type) {
  return res.status(400).json({ message: 'Team default conferencing app unavailable' });
}

Type guard

function isUsableTeamConferencingApp(slug: string): boolean {
  return !!getAppFromSlug(slug)?.appData?.location?.type;
}

Try / catch

null

Prevention

Validate the team's stored slug resolves to a valid conferencing app before bulk update.
Migrate team metadata slugs across app renames.
Prompt team admins to re-select a default when an app is removed.

When it happens

Trigger: Team metadata.defaultConferencingApp.appSlug is set but getAppFromSlug returns undefined, or the found app has no appData.location.type. Occurs after an app is uninstalled/renamed/disabled while the team default still references it.

Common situations: App slug renamed across versions; app package removed; team metadata edited manually; app feature-flagged off; non-conferencing app mistakenly set as the team default.
