java.lang.NoSuchMethodError: com.mongodb.Mongo.<init>(Lcom/mongodb/MongoClientURI - mongodb

Question

I am very new to scala spark and Mongo. while trying to load some data to MongoDB by spark with the following code.
import com.mongodb.spark.config.WriteConfig
import com.mongodb.spark.toDocumentRDDFunctions
import org.apache.spark.sql.SparkSession
import org.apache.spark.{SparkConf, SparkContext}
import org.bson.Document
object MongoTest {
def main(args: Array[String]): Unit = {
val spark = SparkSession.builder()
.master("local[*]")
.appName(this.getClass.getSimpleName)
.getOrCreate()
val conf = new SparkConf().setAppName(this.getClass.getSimpleName).set("spark.driver.allowMultipleContexts", "true")
val sc = new SparkContext(conf)
val documents = sc.parallelize((1 to 10).map(i => Document.parse(s"{test: $i}")))
documents.saveToMongoDB(WriteConfig(Map("spark.mongodb.output.uri" -> "mongodb://127.0.0.1:27017/sampledb.testMongo")))
}
}
The error occurs and my spark submit fails with following error:

I use Spark version 2.4.0 and Scala version 2.11.12. Any idea where I am wrong.?
