The error "Property description is required for listings" occurs when a list-side transaction is submitted to dash without the Property Description filled in on the Features tab of the property record
To resolve the error, the transaction needs to be resubmitted with the Property Description field added:
If the property description for the listing is not known, or not yet available, users may enter the words "Coming Soon!" or simply enter a space in the remark text field to pass the validation check for submission.
