AiLogNotFound

Error message

ResponseCode.AiLogNotFound

What it means

DraftGenerationService.getTask fetches an AI log by id AND (userId, userType) via aiLogRepository.getByIdAndUserId; when no document matches, it throws AppException(ResponseCode.AiLogNotFound). The ownership scoping means a valid task id belonging to another user is indistinguishable from a nonexistent id.

Solutions

1. Verify the taskId belongs to the authenticated userId/userType making the request
2. Re-create the task if the id came from another environment or expired retention window
3. Confirm the userType in the auth context matches the one used at task creation
4. Handle AiLogNotFound in the polling client as a terminal 'task unknown' state instead of retrying forever

Example fix

// before
const task = await getTask(taskId, currentUserId, UserType.User) // taskId owned by another user
// after
const ownedTaskIds = (await listTasks({ taskIds: [taskId] }, currentUserId, UserType.User))
if (!ownedTaskIds.length) throw new AppException(ResponseCode.AiLogNotFound) // fail fast client-side, don't poll foreign ids

// client-side: only poll ids returned by your own create call, persisted with the same auth context
if (!createdTaskIds.includes(taskId)) {
  throw new Error(`taskId ${taskId} was not created by this user/session`)
}

try {
  const task = await draftGenerationService.getTask(taskId, userId, userType)
} catch (e) {
  if (e instanceof AppException && e.code === ResponseCode.AiLogNotFound) {
    return { status: 'unknown' } // stop polling; do not retry
  }
  throw e
}

When it happens

Trigger: Polling a draft-generation task with a taskId that does not exist, was created by a different userId/userType, or with a JWT/auth context whose userType differs from the one recorded on the log (e.g. querying as user vs admin/agent type).

Common situations: Client polls with a task id from a previous environment/database; auth token rotated so the userId no longer matches the log owner; task id truncated or type-confused (stringified ObjectId vs custom id); calling getTask before task creation was persisted.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
