> The problem with {{FieldsDataType}} is that the method {{getFieldDataTypes}} does not keep the order of the fields stored in the logical type. Therefore at couple of locations we have to first iterate over the names in logical type and then get the DataTypes.
> {code}
> final RowType rowType = (RowType) fieldsDataType.getLogicalType();
> final String[] fieldNames = rowType.getFields()
> 	.stream()
> 	.map(RowType.RowField::getName)
> 	.toArray(String[]::new);
> final TypeInformation<?>[] fieldTypes = Stream.of(fieldNames)
> 	.map(name -> fieldsDataType.getFieldDataTypes().get(name))
> 	.map(LegacyTypeInfoDataTypeConverter::toLegacyTypeInfo)
> 	.toArray(TypeInformation[]::new);
> {code}
