>                 Key: NIFI-7881
>                 URL: https://issues.apache.org/jira/browse/NIFI-7881
>             Project: Apache NiFi
>          Issue Type: Bug
>          Components: Core Framework
>    Affects Versions: 1.10.0, 1.9.2, 1.11.4, 1.12.1
>            Reporter: Dominik Przybysz
>            Priority: Major
>
> I have two schemas - input one has Map<String, UNION<null, String, Double>> field and output schema has the same field with type Map<String, UNION<null, String>>.
> In such example Double should be coerced to String, but it is still Double and processor fails to write avro object because of incompatible field type.
> I created two similar tests:
> - for AvroRecordConverter (used by ConvertAvroSchema) which fails
> - for AvroTypeUtil (used in some other components which write avro objects) and here the test passes
> The tests are here: https://github.com/alien11689/nifi/commit/87f890b33efd232297b79bbe19ba6cd05d36e614
