> JsonTreeReader: schema inference gives wrong result
> ---------------------------------------------------
>
> Key: NIFI-10957
> URL: https://issues.apache.org/jira/browse/NIFI-10957
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.16.3, 1.19.0
> Reporter: Jean-Pierre Milhau
> Priority: Major
>
> I am using the JsonTreeReader with the schema access strategy set to Infer
> schema.
>
> For the following data in input:
> {code:java}
> {"alt": 12}
> {"alt": null}{code}
> the inferred schema gives field "alt" as a nullable INT, what is good.
>
> But for the following data in input:
> {code:java}
> {"location": {"alt": 12}}
> {"location": {"alt": null}}{code}
> the inferred schema gives field "alt" (inside record "location") as a
> nullable CHOICE(STRING, INT), what seems to me incorrect because there is no
> string value for field "alt". I am expecting field "alt" as a nullable INT as
> when it is on the root of the json document.
