In case your implementation uses parallel processing (e.g. jobs queue processed by multiple very fast workers/lambda functions) your requests are also processed in parallel up to some limit. You can get 422 errors caused by low level DB constraints e.g. if you try to create agendas with same email_alias in parallel.
