This fixes [Issue 38005](https://github.com/apache/airflow/issues/38005). Result: Now EMRServerlessStartJobOperator is able to utilize partial/expand functionality of Airflow. Previously, the following DAG code will fail to serialize in the webserver: ```python from datetime import datetime from airflow.models.dag import DAG from airflow.providers.amazon.aws.operators.emr import ( EmrServerlessStartJobOperator, ) DAG_ID = "example_emr_serverless" emr_serverless_app_id = "01234abcd" role_arn = "arn:test" with DAG( dag_id=DAG_ID, schedule="@once", start_date=datetime(2021, 1, 1), tags=["example"], catchup=False, ): start_job = EmrServerlessStartJobOperator.partial( task_id="start_emr_serverless_job", application_id=emr_serverless_app_id, execution_role_arn=role_arn, configuration_overrides={ "monitoringConfiguration": {"s3MonitoringConfiguration": {"logUri": f"s3://test/logs"}} }, ).expand( job_driver=[{ "sparkSubmit": { "entryPoint": "test.jar", "entryPointArguments": ["--arg", "1"], "sparkSubmitParameters": "--conf sample", } },{ "sparkSubmit": { "entryPoint": "test.jar", "entryPointArguments": ["--arg", "2"], "sparkSubmitParameters": "--conf sample", } }] ) ``` After this PR, the above DAG should be serialized successfully. <!-- Licensed to the Apache Software Foundation (ASF) under one or more contributor license agreements.
