Hi, We have been testing GeoServer STAC and have got it mostly working: http://86.50.229.158:8080/geoserver/ogc/stac/
The last minor problem is that search with a filter does not work, although conformance page gives hope for that: [ http://86.50.229.158:8080/geoserver/ogc/stac/conformance?f=text%2Fhtml | http://86.50.229.158:8080/geoserver/ogc/stac/conformance?f=text%2Fhtml ] Also collections Queryables page looks ok: [ http://86.50.229.158:8080/geoserver/ogc/stac/collections/sentinel2_full_test/queryables | http://86.50.229.158:8080/geoserver/ogc/stac/collections/sentinel2_full_test/queryables ] We have been testing mostly with pystac-client Python package, but the same error is given by API request: [ http://86.50.229.158:8080/geoserver/ogc/stac/search?f=application%2Fgeo%2Bjson | http://86.50.229.158:8080/geoserver/ogc/stac/search?f=application%2Fgeo%2Bjson ] POST {"limit": 1, "datetime": "2021-08-01T00:00:00Z/2022-12-01T23:59:59Z", "collections": ["sentinel2_full_test"], "filter": {"op": "lte", "args": [{"property": "eo:cloud_cover"}, 10]}, "filter-lang": "cql2-json"} The error in the log is: 24 Jan 11:26:35 ERROR [geoserver.ogcapi] - Failed to dispatch API request java.lang.NullPointerException at org.geoserver.ogcapi.stac.TemplatePropertyMapper.mapFilter(TemplatePropertyMapper.java:142) at org.geoserver.ogcapi.stac.TemplatePropertyMapper.mapPropertiesInternal(TemplatePropertyMapper.java:59) at org.geoserver.ogcapi.stac.TemplatePropertyMapper.mapProperties(TemplatePropertyMapper.java:49) at org.geoserver.ogcapi.stac.QueryResultBuilder.parseFilter(QueryResultBuilder.java:508) at org.geoserver.ogcapi.stac.QueryResultBuilder.build(QueryResultBuilder.java:301) at org.geoserver.ogcapi.stac.STACService.searchPost(STACService.java:480) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.geoserver.ogcapi.APIConfigurationSupport$APIInvocableHandlerMethod.doInvoke(APIConfigurationSupport.java:64) at org.springframework.web.method.support.InvocableHandlerMethod.invokeForRequest(InvocableHandlerMethod.java:138) at org.springframework.web.servlet.mvc.method.annotation.ServletInvocableHandlerMethod.invokeAndHandle(ServletInvocableHandlerMethod.java:105) at org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter.invokeHandlerMethod(RequestMappingHandlerAdapter.java:878) at org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter.handleInternal(RequestMappingHandlerAdapter.java:792) at org.springframework.web.servlet.mvc.method.AbstractHandlerMethodAdapter.handle(AbstractHandlerMethodAdapter.java:87) at org.geoserver.ogcapi.APIDispatcher.handleRequestInternal(APIDispatcher.java:284) at org.springframework.web.servlet.mvc.AbstractController.handleRequest(AbstractController.java:177) at org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter.handle(SimpleControllerHandlerAdapter.java:52) at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:1043) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:943) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:1006) at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:909) at javax.servlet.http.HttpServlet.service(HttpServlet.java:696) We have been removing fields from default database and from default templates, but basic search is working ok, for example POST with {"limit": 1, "datetime": "2021-08-01T00:00:00Z/2022-12-01T23:59:59Z", "collections": ["sentinel2_full_test"], "intersects": {"type": "Point", "coordinates": [25.6, 65.1]}} So I am not sure where to look next.. Any ideas? In Global Queryables we have at the moment: id, geometry, eo:cloud_cover Not actually sure, what should be used here, DB field names or STAC attribute names or some EO-Search names. ** A comment about EO-search packaging, it seems that gt-cql-json-28.0.jar is required by 2.22.0 GeoServer, but that .jar is currently not included in GeoServer packages, so I added it manually added from GeoTools https://sourceforge.net/projects/geotools/files/GeoTools%2028%20Releases/28.0/ Best regards, Kylli Ek GIS-coordinator CSC - IT Center for Science Ltd PL 405, 02101 Espoo Tel: +358 50 38 12 838 gisco...@csc.fi
