Yield not stopping the flow in ember concurrency task

Question

if (isEmpty(contact) || isEmpty(get(contact, 'emails'))) {
  contact = yield store.findRecord('contact', contactId);
}

if (isEmpty(contact) || isEmpty(get(contact, 'emails'))) {
  flashMessages.danger(i18n.t('email.cpq_document_email_missing'));
  return false;
}

The second block runs when the promise is running and Im getting an error. Shouldn't it stop the flow until the promise is resolved.

The promise runs fine and it works the next time

Assuming you are using ember-data, you may be encountering a case where findRecord returns a cached record. This depends on if you've already loaded the record (perhaps from a previous findRecord, findAll or query on another route, and how the ember-data adapter is configured: shouldBackgroundReloadRecord and shouldBackgroundReloadAll are methods on the adapter that default to returning true. When those methods return true, the cached record is immediately returned, but the record(s) are fetched again in the "background".
