Hi, I'm planning to use the lattice suggester in Calcite with TPC-DS, but the TpcdsLatticeSuggesterTest in Calcite fails in the 1st query. I run the TpcdsLatticeSuggesterTest with Disabled annotation removed.
The error is shown below: Can't unwrap class org.apache.calcite.sql.SqlDialect from RelOptTableImpl{schema=org.apache.calcite.prepare.CalciteCatalogReader@54fcf62e, names= [tpcds, STORE_RETURNS],
