What causes "App not found with id "${workspaceApp._id}"" in Budibase/budibase?

Refresh the workspace apps list before toggling if it may be stale

App not found with id

Error message

App not found with id "${workspaceApp._id}"

What it means

After updating a workspace app via the API, edit() syncs the local store by finding the app's index by _id. If the updated app no longer exists in the local store list (index -1), it throws, indicating store state is out of sync with the server.

Solutions

Refresh the workspace apps list before toggling if it may be stale
Check the app wasn't deleted in another tab/session; re-fetch via API.workspaceApp.fetch
Verify the workspaceAppId passed to toggleDisabled is correct
If hit inside edit() after a successful API update, reload the store state and retry

Example fix

// before
await workspaceApps.toggleDisabled(appId, true)
// after
const exists = get(workspaceApps).workspaceApps.some(a => a._id === appId)
if (!exists) await workspaceApps.fetch()
await workspaceApps.toggleDisabled(appId, true)

Defensive patterns

Strategy: retry

Validate before calling

const existsLocally = get(workspaceApps).workspaceApps.some(a => a._id === appId)
if (!existsLocally) await workspaceApps.fetch()

Try / catch

try {
  await workspaceApps.toggleDisabled(appId, state)
} catch (e) {
  if (e.message.startsWith("App not found with id")) {
    await workspaceApps.fetch()
    // re-check and inform user the app no longer exists
  } else throw e
}

Prevention

Refresh the workspace apps list after external changes
Avoid holding app ids across long-lived sessions without refresh
Verify ids passed to toggleDisabled come from current store state
Handle multi-tab deletion scenarios in the UI

When it happens

Trigger: toggleDisabled(workspaceAppId) calls edit() for an app id that was removed from the store (deleted elsewhere/concurrently) or never present locally, even though the API update succeeded.

Common situations: Two browser tabs — one deletes the app while the other toggles it; stale store after external deletion; passing a wrong/nonexistent _id to toggleDisabled; store not refreshed after another user's changes.
