Description

Consider the following Avro Schema:

{
    "name" : "test",
    "type" : "record",
    "fields" : [ {
        "name" : "field1",
        "type" : {
            "type" : "map",
            "values" : "string"
        }
    } ]
}

and corresponding JSON data adhering to the schema:

[{
    "field1": {
        "toto" : "v1",
        "titi" : "v2"
    }
}]

ValidateRecord marks the record as invalid though it should be valid. The message in the provenance event is "Record #1 is invalid due to:
MapRecord[

{toto=v1, titi=v2}

] is not a valid value for /field1: Value is of type org.apache.nifi.serialization.record.MapRecord but was expected to be of type MAP[STRING]".
