Could you run these and paste back what you get, this will help figure out the any access issues to the schema:
SELECT schemata.schema_name, tables.table_name
FROM system.information_schema.schemata AS schemata
LEFT JOIN system.information_schema.tables AS tables
ON tables.table_catalog = schemata.catalog_name
AND tables.table_schema = schemata.schema_name
WHERE schemata.catalog_name = 'lhr';
and
SELECT extension_name, extension_version FROM duckdb_extensions() WHERE loaded;
will tell us the loaded extensions. Thanks!
