apps/worker/src/tasks/sync-all/processor.ts:50
🗄️ Data Integrity & Integration | 🔴 Critical | 🏗️ Heavy liftRoute the flow jobs to
Queues.WORKERand wrap their payloads as{ task, data }.After this PR,
apps/worker/src/index.tsstarts only one worker, forQueues.WORKER. The per-task queues have no worker. TheseflowProducer.adddefinitions still usequeueName: Tasks.SYNC_AUTHOR,Tasks.SYNC_POSTandTasks.SYNC_COLLECTION, and they still pass the raw task input asdata. As a result:
- No worker ever processes the sync-author, sync-post or sync-collection jobs that sync-all creates.
- If you change only the queue name, the dispatcher in
apps/worker/src/queues/worker.tsreadsjob.data.taskasundefinedand throws "Could not locate the processor".Every full sync stops working without any error.
🐛 Proposed fix (apply the same pattern to all four definitions)
const authorJobDef: FlowJobNode = { name: author.path, data: { - author: author.path, - branch: BRANCH_MAIN, - ref: job.data.ref, - installation, - } satisfies TaskInputs[typeof Tasks.SYNC_AUTHOR], - queueName: Tasks.SYNC_AUTHOR, + task: Tasks.SYNC_AUTHOR, + data: { + author: author.path, + branch: BRANCH_MAIN, + ref: job.data.ref, + installation, + } satisfies TaskInputs[typeof Tasks.SYNC_AUTHOR], + } satisfies QueueInputs[typeof Queues.WORKER], + queueName: Queues.WORKER, };Also applies to: 73-73, 119-119, 134-134

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick winRoute webhook sync jobs through the worker queue.
When a push or pull-request webhook contains content changes,
flowProducer.add(jobDef)enqueues the nodes created byconstructSyncJobs. Those nodes targetTasks.SYNC_*, but the only registered worker consumesQueues.WORKER. The sync jobs can therefore remain unprocessed. Set each node's queue toQueues.WORKERand wrap its input as{ task, data }, which is the payload shape thatapps/worker/src/queues/worker.tsdispatches.Suggested fix

5-5: 🗄️ Data Integrity & Integration | 🔵 TrivialDrain or migrate the jobs that are already in the old per-task queues before you deploy.
After this change, no worker listens on the old per-task queues. This includes
delete-s3-object, which uses a delayed grace period. Jobs that are pending or delayed in those queues at deploy time will never run. For example, S3 deletions that were already scheduled will not happen, and the objects stay in S3. The oldcleanup-attachmentsscheduler also stays in Redis.Plan a one-time step for this deploy. Choose one of these options:
- Re-enqueue the old jobs through
createJob.- Keep the old workers running until their queues are empty.
After that, remove the old scheduler with
removeJobScheduler.🤖 Prompt for AI Agents

Creates one "worker" queue that delegates to all of the task types (by importing all of the processors).
This enables the worker machine to set one
concurrency: 1limit, and actually have one task running per machine, rather than applying that limit per task type.This also means bullmq will reuse the same thread pool for different tasks types, rather than managing a separate pool for each worker.
