As the error message indicates, you need to enable the "avro" feature on datafusion

Edit your Cargo.toml, replacing the datafusion dependency with

datafusion = { version = "12.0.0", features = ["avro"] }

(the version can be whatever you need it to be)

If you already had features enabled for datafusion, you just need to add "avro" to the list.
