Oscar Westra van Holthe - Kind commented on AVRO-3791:
------------------------------------------------------
The associated PR has been merged both to {{branch-1.12}} and to {{{}main{}}},
and thus will be released with both 1.12.1 and 1.13.0.
However, the change will appear to be missing from 1.13.0, as the change is not
in the fastreader implementation (which will be enabled by default in 1.13.0).
As such, I'll mark this issue as "fixed in 1.12.1", but keep it unresolved.

> Key: AVRO-3791
> URL: https://issues.apache.org/jira/browse/AVRO-3791
> Project: Apache Avro
> Issue Type: Improvement

> Reporter: Logan Donoughe
> Priority: Trivial
> Labels: pull-request-available
> Time Spent: 1h 40m
> Remaining Estimate: 0h

> When working with Avro and Flink, I've run into errors like this fairly
> often:
> {code:java}
> java.io.IOException: Failed to deserialize consumer record due to
> ...
> Caused by: org.apache.avro.AvroTypeException: Found null, expecting string
> at
> org.apache.avro.io.ResolvingDecoder.doAction(ResolvingDecoder.java:308) {code}
> At a glance, this is not particularly useful. I know that some field is
> getting a null where there is a non-nullable string but in order to find out
> which one it is I either have to check all possible non-null string fields
> for null values, look at which columns are changed recently and guess and
> check, or throw a debugger in and dive down the stack. So far, the last has
> been the fastest for me.
> Ideally, I would like the error message to tell me which field has the null
> value so I can fix the problem with high confidence and without the use of a
> debugger.
