Unable to create layers from Generalizing DataStore

[Alexandre Gacon]

Context:

• GS Cloud with JDBC config and JDBC resource store
• Data are stored in a Postgis Database

Reproduced with:

• GS Cloud RC1.28 on Kubernetes deployed with Helm charts
• GS Cloud RC1.28 on Docker deployed with docker compose
• GS Cloud RC1.29 On Docker deployed with docker compose
• GS Cloud master code from GitHub deployed with docker compose

In all cases, when I try to create a layer from a generalizing DataStore from admin UI, I always have the following message:
Caused by: java.lang.NullPointerException: Cannot invoke "java.io.File.exists()" because "f" is null at org.geoserver.data.gen.DSFinderRepository.getURLForLocation(DSFinderRepository.java:46) at org.geotools.data.gen.DSFinderRepository.getMapFromPropetryLocation(DSFinderRepository.java:81) at org.geotools.data.gen.DSFinderRepository.dataStore(DSFinderRepository.java:114) at org.geoserver.data.gen.DSFinderRepository.dataStore(DSFinderRepository.java:69) at org.geotools.data.gen.PreGeneralizedFeatureSource.getBaseFeatureSource(PreGeneralizedFeatureSource.java:113) at org.geotools.data.gen.PreGeneralizedFeatureSource.getSchema(PreGeneralizedFeatureSource.java:357) at org.geotools.data.gen.PreGeneralizedFeatureSource.getSchema(PreGeneralizedFeatureSource.java:67) at org.geoserver.catalog.CatalogBuilder.buildFeatureType(CatalogBuilder.java:342) at org.geoserver.catalog.CatalogBuilder.buildFeatureType(CatalogBuilder.java:325) at org.geoserver.web.data.layer.NewLayerPage.buildLayerInfo(NewLayerPage.java:421) ... 119 more

The problem was a configuration problem, with a wrong reference to the datastore giving access to the tables.
