AWS Glue ETL Job: IllegalArgumentException: Missing collection name.

Hi, I have defined a crawler that connects to monngodb and created a datacatalog table successfully. I am trying to define an etl job that will write to aws rds instance. I am getting the following error when running the etl job: IllegalArgumentException: Missing collection name. Set via the 'spark.mongodb.input.uri' or 'spark.mongodb.input.collection' property I added a definition in the data catalog table for database and collection and yet keep getting this error. What is missing? Thanks!
