What happened?

When I'm trying to call an asynchronous API inside a policy pack, it generates this error:
"error: Exception calling application: There is no current event loop in thread 'ThreadPoolExecutor-0_0'. ".
Even if I add async/await to the function or even using pulumi.routine.sync_await the asyncronous call doesn't work.
I think is missing the asyncio.get_event_loop() function in the generation of the thread when is called the policy Pack.

This is the function:

def validator(args: ResourceValidationArgs, report_violation: ReportViolation):
    if args.resource_type != "aws:s3/bucket:Bucket":
        return
    
    resource =_sync_await(aws.pricing.get_product(
    service_code="AmazonS3",
    filters= [
        aws.pricing.GetProductFilterArgs(field = "productFamily", value = "Storage"),
    ]))
    if resource is None:
        report_violation("The resource has not been found")
    else:
        print(resource)
    if resource["price"] > 0:
        report_violation("The resource has a cost")
    else:
        report_violation("The resourse is free")

Expected Behavior

I would expect that at least the function generates an output but it doesn't.

Steps to reproduce

Create a policy pack.
Add the function written in the description.
Create a ResourceValidationPolicy and a PolicyPack
Try to execute it with a project.

Output of pulumi about

error: Exception calling application: There is no current event loop in thread 'ThreadPoolExecutor-0_0'
