What step must a landscape designer take if they encounter an error while using the Create Features pane?

A landscape designer encountering an error while using the Create Features pane must ensure they have an editable layer added to the map. The Create Features pane is dependent on having layers that allow for feature creation, which means that without an editable layer, no new features can be created, and errors will arise.

Editable layers have specific properties set that permit alterations and additions to the data they contain. If the designer is attempting to add features but their active layer is not editable, ArcGIS will generate an error, preventing them from making any changes. Therefore, the designer must add an appropriate editable layer to continue their work smoothly.

Enabling editing on the map or managing edits might seem relevant, but those actions do not directly resolve issues related to the absence of editable layers. Similarly, enabling Feature Analysis on the Portal isn't related to the creation of new features within the Create Features pane.
