Therefore, it is recommended to ensure the geometry complexity of the snap layers is appropriate for the specified scale ranges to avoid overloading the server with the GetFeatureInfo requests. Also, the QGIS project will need to be configured so that snap layers are queryable and that feature info responses contain geometries.
