Resolved
This has been resolved across all affected environments.
Monitoring
We have found the cause of the problem and are undoing the recent update that introduced it.
Adding vaccinations and other medications with batches should start working again within the next few minutes.
If you still see the error after that, please refresh the page.
We are also working on a permanent fix and will post another update once everything is confirmed to be working.
Investigating
We are aware of an issue in Provet where adding a vaccination or other medication that uses batch tracking to a consultation fails with an "Invalid input" error. Items without batch tracking and the rest of Provet are working normally.
We have identified a recent update as the likely cause and are working on reverting it. We will post another update as soon as the fix is live, or within 60 minutes.
We apologise for the disruption to your clinical work.
