Summary: ValidateRecord reports false positive for avro arrays with null elements Key: NIFI-7925 URL: https://issues.apache.org/jira/browse/NIFI-7925 Project: Apache NiFi Issue Type: Bug Affects Versions: 1.12.1 Reporter: Christophe Monnet with this avro schema: { "type": "record", "name": "simple", "fields": [{ "name": "stuff", "type": { "type": "record", "name": "stuff", "namespace": "simple", "fields": [{ "name": "languages", "type": { "type": "array", "items": ["null", "string"] }, "doc": "" } ] }, "doc": "" } ] } and this payload: {"stuff":{"languages":[null]}} ValidateRecord fails with Records in this FlowFile were invalid for the following reasons: ; The following 1 fields had values whose type did not match the schema: [/stuff/languages] But when using avrotool I can convert the payload: $ avrotool fromjson --schema-file schema.json payload.json > payload.avro $ avrotool tojson payload.avro {"stuff":{"languages":[null]}} Moreover with this payload {"stuff":{"languages":[]}} ValidateRecord routes to the valid queue. Therefore I suspect that ValidateRecord has a bug when it comes to arrays with nullable items. -- This message was sent by Atlassian Jira (v8.3.4#803005)
