#1964 bug: EmptySchemaTypeError on replication-key for entities configured Issue created by mertbakir ### Singer SDK Version 0.31.1 ### Is this a regression? • Yes ### Python Version 3.10 ### Bug scope Taps (catalog, state, etc.) ### Operating System Ubuntu ### Description Entities configured as

FULL_TABLE

replication, should not be affected by the replication-key. Meltano yaml below sets replication-key for public-table01 too, and the code crashes since public-table01 has no such column.

metadata:
      "public-*":
        replication-method: INCREMENTAL
        replication-key: update

      public-table01:
        replication-method: FULL_TABLE
