----------------------------------
[~jamesmcguirepro] could you provide more info? I'd like to take a look the
detail.

> Key: FLINK-30158
> URL: https://issues.apache.org/jira/browse/FLINK-30158
> Project: Flink
> Issue Type: Bug
> Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile), Table
> SQL / Ecosystem
> Affects Versions: 1.16.0
> Reporter: James Mcguire
> Priority: Major
>
> I am encountering a {{java.lang.NullPointerException}} exception when trying
> to use Flink SQL to query a kafka topic that uses either {{repeated}} and/or
> {{map}} attributes.
>
> {*}{*}{*}Replication{*} *steps*
> # Use a protobuf definition that either uses repeated and/or map. This
> protobuf schema should cover a few of the problematic scenarios I ran into:
>
> {code:java}
> syntax = "proto3";
> package example.message;
> option java_package = "com.example.message";
> option java_multiple_files = true;
> message NestedType {
> int64 nested_first = 1;
> oneof nested_second {
> int64 one_of_first = 2;
> string one_of_second = 3;
> }
> }
> message Test {
> repeated int64 first = 1;
> map<string, NestedType> second = 2;
> } {code}
> 2. Attempt query on topic, even excluding problematic columns:
