IllegalArgumentException: requirement failed: Invalid uri

I used these settings to create the spark session:

spark = SparkSession.builder \
    .appName(appName) \
    .config("spark.mongodb.input.uri", "mongodb+srv://user:password@cluster.url.net/databasename?retryWrites=true&w=majority") \
    .config("spark.mongodb.output.uri", "mongodb+srv://user:password@cluster.url.net/databasename?retryWrites=true&w=majority") \
    .getOrCreate()

These for writing:

# Create dataframe named df
df.write.format("mongo").option('spark.mongodb.output.collection', 'collection_name')\
    .mode("append") \
    .save()

And these for reading:

# Read data from MongoDB
df = spark.read.format('mongo').option("spark.mongodb.input.collection", "collection_name").load()
df.printSchema()
df.show()

Hope this help!!
