Delta live table UC Kinesis: options overwriteschema, ignorechanges not supported for data sourc

I try to build a DLT in UC with Kinesis as producer.

My first table looks like: 

 

@dlt.create_table(
table_properties={
"pipelines.autoOptimize.managed": "true"
},
spark_conf={"spark.databricks.delta.schema.autoMerge.enabled": "true"},
)

def feed_chunks():
return (
spark.readStream.format("kinesis")
.option("streamName", stream_name)
.option("ignoreChanges", "true")
.option("overwriteSchema", "true")
.option("roleArn", "arn:aws:iam::xxxxx:role/xxxxx-read-role")
.option("region", "eu-west-1")
.load()
)

And I get this error:

pyspark.errors.exceptions.AnalysisException: [UNSUPPORTED_STREAMING_OPTIONS_PERMISSION_ENFORCED] 
Streaming options overwriteschema, ignorechanges are not supported for
data source kinesis on a shared cluster.

Is this a know limitation of DLT x UC ?

The same DLT with simple hive metastore works fine.

If you use the "Preview" Channel in the "Advanced" section of the DLT Pipeline, this error should resolve itself. This fix is planned to make it into the "Current" channel by Aug 31, 2023

Hello !

My pipeline is already in Advanced mode because I'm using Unity Catalog in storage options
