Azure Synapse: Merge command with the identity column in target table is not working

The Merge command on the target table with the identity column gives an error although we are not updating/inserting the identity column. Please find the below snippet and error message

CREATE TABLE dbo.t1 (id INT IDENTITY(1,1), Sub INT, Metric INT) WITH (DISTRIBUTION = HASH(Sub), CLUSTERED COLUMNSTORE INDEX);

;WITH SRC AS (SELECT 1 AS Sub, 100 AS Metric) MERGE dbo.t1 AS tgt USING SRC ON tgt.Sub = SRC.Sub WHEN MATCHED THEN UPDATE SET Metric = SRC.Metric WHEN NOT MATCHED THEN INSERT (Sub, Metric) VALUES (SRC.Sub, SRC.Metric);
