The below error occurs when attempting to publish a Nintex workflow that contains a conditional start event.

Error message:

Error publishing workflow. Conditions could not be published and the workflow will not be able to start conditionally. Please try publishing again.

Publishing a Nintex conditional workflow will use 1 subscription per published workflow. SharePoint only allows 100 subscriptions on a custom list and it is possible that the list has reached the maximum number. Other third party products can also use subscriptions for example Microsoft Flow.

Options:

1. Recreate the SharePoint list.
2. Contact Microsoft Support to assist with removing subscriptions from the SharePoint list.
