+
+    You need to add `TEMPLATE "void"` to each of the layers you want to make available through the OGC Features API. 
+    [TEMPLATE](https://mapserver.org/mapfile/layer.html#mapfile-layer-template) is a left-over from when HTML templates were used to return features, and allows the layer to be queried.
