> Project: Spark
> Issue Type: Bug
> Components: Connect
> Affects Versions: connect-rust-4.3.0

> In PySpark Connect, {{StructType[name]}} raises the {{PySparkKeyError}}
> {{KEY_NOT_EXISTS}} of the name for a field that does not exist, and
> {{StructType.add(field, data_type)}} parses a str {{data_type}} as the JSON
> value of a data type, such as "integer", raising {{CANNOT_PARSE_DATATYPE}}
> for one that is not, such as "int".
> The Rust-backed Python client raises a plain {{KeyError}} for a field that
> does not exist, and parses a str of {{add}} as DDL. Take them as PySpark does.
