How to fix this issue

Your data is missing a geometry.

The Tree guidance explains how to fix the issue:

geometry

The boundary of the tree as a single polygon or multipolygon value. All points in the polygon must be in the WGS84 coordinate reference system.

If you’re providing geometry in a CSV, geometry should be in well-known text (WKT).

You must provide a point or geometry for each tree. You may provide both.

Example: MULTIPOLYGON (((1.188829 51.23478,1.188376 51.234909,1.188381 51.234917,1.187912 51.235022...

If you’re providing geometry in a GeoJSON, GML or Geopackage, use the associated geometry format.
