### Please describe the bug 🐞

df = pyarrow.read_table(read_dictionary=[string_columns])

Beginne damit, das Problem mit pyarrow.read_table(read_dictionary=[string_columns]) und einer Tabelle zu reproduzieren, die aus catalog.load_table(table_name) geladen wurde. Vergleiche table.append(df), table.upsert(df, join_cols=[primary_keys]) und table.update(df, join_cols=[primary_keys]); abgeschlossen ist die Aufgabe, wenn upsert und update Dictionary-kodierte Spalten ohne den gemeldeten Invalid Type Dictionary-Fehler verarbeiten.
