Unable to access PartitionContext or get PartitionId when using EventHubTrigger

While using EventHubTrigger, unable to access PartitionContext. Also I am not finding any other way to access the partition Id.
Please find below the code. On trying to get PartitionContext using @BindingName, partitionContext object is null.

```
@FunctionName("EhbExample")
@StorageAccount("AzureWebJobsStorage")
public void run(
@EventHubTrigger(name = "msg", cardinality = Cardinality.MANY, eventHubName = "%SourceEHName%", connection = "SourceEHConnString", consumerGroup = "%SourceEHConsumerGrp%") List eventData,
final ExecutionContext context, @BindingName("SystemPropertiesArray") SystemProperty[] systemProperties,
@BindingName("PartitionContext") PartitionContext partitionContext ) {
Logger log = context.getLogger();
log.info("Triggered Function App");

log.info("Partition Id: " + partitionContext.getPartitionId());
