Hi, I use `AvroSchemaConverter` to converts flink logical type into an avro
schema will be throw `SchemaParseException` when there are both row type and
row array type
This is my simplified code
{code:java}
RowType rowType = (RowType) TableSchema.builder()
.field("row", DataTypes.ROW(DataTypes.FIELD("string_field",
DataTypes.STRING())))
.field("row_array", DataTypes.ARRAY(DataTypes.ROW(DataTypes.FIELD("int_field",
DataTypes.STRING()))))
.build().toRowDataType().getLogicalType();
Schema schema = AvroSchemaConverter.convertToSchema(rowType);
System.out.println(schema);
{code}
it will throw
{code:java}
