Fixes:

  • Fixed an incorrect value in the vehicle dropdown in the «Vehicle orientation detection policy» field in the «Zone flow» handler. Values now display correctly;
  • Adjusted the layout of the lower border for the parameter groups;
  • Fixed an issue with saving images in list items: an image added via the filter when creating a list item now saves correctly;
  • Fixed an issue when saving a camera after changing the source type: switching between source types now works correctly without required-field errors and without blocking saving changes;
  • Fixed filter search in the Events/Incidents sections: when entering values manually, dropdown search now matches only by key and no longer searches by UUID;
  • Adjusted error display when deleting a recognition zone used in a scenario handler: the user now sees a single error message instead of two;
  • Fixed an issue with opening the API documentation in the deployment package. Documentation now opens without VPN and works correctly.
