When a user submits a ticket via the Thread Slack app and their Slack account is not linked to a contact record in HaloPSA, the ticket is created blank with no user information. This makes it difficult to identify and resolve the issue quickly. The request is to add an automatic error message or notification in Slack when a ticket is submitted by someone who is not listed as a client contact in HaloPSA. The message could clearly state that the submitter is not in the client contact list, helping administrators address the problem and ensure proper mapping.
