We use a standalone server (SQL server source) with an iceberg sink
(ghcr.io/memiiso/debezium-server-iceberg:1.0.0.Beta1)
We also have a few iceberg.sink parameters

debezium.sink.batch.batch-size-wait=MaxBatchSizeWait
debezium.sink.batch.batch-size-wait.max-wait-ms=300000
debezium.sink.batch.batch-size-wait.wait-interval-ms=1000

When we activate theese parameters we have an error
