We were made aware of an issue at approx. 08:09 this morning preventing new patients from being created. This issue was caused as we introduced validation checks against the referrer name in the system in order to streamline our codebase.
This caused an error to appear due to the presence of invalid data in our database and more specifically an empty referrer was selected. To resolve this, a SQL query was run to update the invalid entries to "Deleted – Do not use", restoring functionality by 08:36.
There is no downstream impact, and we will review and optimise the validation logic in a future release.
