> After upgrading from 1.15.3 to 1.18.0 we saw some issue regarding AvroReader when the following conditions are met:
>  # The AVRO schema in the flowFile uses the "aliases" attribute
>  # There is a record in the flowFile where a field with set alias has a value of "null"
> The use of aliases and null values used to work for us before upgrading Nifi without issues
> Example schema:
> {code:java}
> {
>   "type": "record",
>   "name": "test",
>   "fields": [
>       { "name" : "id", "type" : "int", "aliases" : ["F1"] },
>       { "name" : "field1", "type" : [ "string", "null" ], "aliases" : ["F2"] },
>       { "name" : "field2", "type" : [ "string", "null" ], "aliases" : ["F3"] }
>  ]
> }
>  {code}
> Example data:
> {code:java}
> [ {
>   "id" : 1,
>   "field1" : "field1content",
>   "field2" : "field2content"
> }, {
>   "id" : 2,
>   "field1" : null,
>   "field2" : "field2content"
> } ]{code}
> Note: If we remove the "aliases" from the schema or make sure that there is never a field with a value of null, we don't have any errors in Nifi 1.18.0.
