autodetect in bigquery.ExternalConfig

[Oliviero]

why when i try to create a 

bigquery.ExternalConfig(

        autodetect = True,

        source_format = bigquery.SourceFormat.PARQUET,

        source_uris = ["{path}"]

    )

i receive the error ?

TypeError: __init__() got an unexpected keyword argument 'autodetect'

The apis says that these attributes are ok to define

https://googleapis.dev/python/bigquery/latest/generated/google.cloud.bigquery.external_config.Extern...

Thanks
