Hi all, Beam 2.55 was released with a bug that causes WriteToJson on Beam YAML to fail when using the Java variant. This also affects any user attempting to use the Xlang JsonWriteTransformProvider - https://github.com/apache/beam/blob/master/sdks/java/io/json/src/main/java/org/apache/beam/sdk/io/json/providers/JsonWriteTransformProvider.java
This is due to a change to https://github.com/apache/beam/blob/master/sdks/java/io/json/build.gradle that removed a dependency on everit which also removed it from being packaged into the expansion service JAR: beam-sdks-java-extensions-sql-expansion-service-2.55.0.jar There is a temporary fix to disable the provider in Beam YAML: https://github.com/apache/beam/pull/30777 I think with the total loss of function, and a trivial fix, it is worth creating a patch release of Beam 2.55 to include this fix. - Jeff
