this issue comes from ErrorHandler of a worker for typename = b, telling there's no handler for typename = a

using different queue to handler different tasks

it means: if there's a task request without a relative handler, you will surely get this error.

@mohit-singh-pepper my workaround is when enqueueing the task i put task name and also the queue name (using asynq.Queue(queueName)).
