Spark create empty delta table on s3

I'm not able to create an empty delta table using create query and then getting error while running merge query.

org.apache.spark.sql.AnalysisException: s3a://bucket/table_t1 is not a Delta table.; at org.apache.spark.sql.delta.DeltaErrors$.notADeltaTableException(DeltaErrors.scala:258)

Create query:

Create table if not exists t1 (pkey varchar(512), name varchar(100)) USING DELTA LOCATION 's3a://bucket/table_t1'
