discrepancy_metrics_request = ",".join(discrepancy_metrics)

Trying to pass None for discrepancy_metrics argument when using create_async_report() throws an error

discrepancy_metrics_request = ",".join(discrepancy_metrics) TypeError: can only join an iterable

The default value are two Ad Network metrics and would produce "broken rows" when trying to pull reports for combined data with the available dimensions and metrics for combined data as discussed in Singular API docs here

None should be an accepted value and possibly the default. I'm not sure why Ad Network metrics are "Discrepancy Metrics" if you were to use this client for Ad Network data pulls, but that is probably just beyond my understanding.
