------------------------------------------
>From the log you posted in the gist it seems that code is still using the
>Flink 1.11.0 version of {{AvroDeserializationSchema}} which doesn't have the
>fix.
You can try and use the snapshots repository and depend on version
{{1.12-SNAPSHOT}}. In maven you can do it by adding this repository:
{code:java}
<repositories>
<repository>
<id>apache.snapshots</id>
<name>Apache Development Snapshot Repository</name>
<url>https://repository.apache.org/content/repositories/snapshots/</url>
<releases>
<enabled>false</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</repositories>

> AvroDeserializationSchema does not work with types generated by avrohugger

> The main problem is that the code in {{SpecificData.createSchema()}} tries to
> reflectively read the {{SCHEMA$}} field, that is normally there in Avro
> generated classes. However, avrohugger generates this field in a companion
> object, which the reflective Java code will therefore not find.
> This is also described in these ML threads:
