Python SDK analytics export to S3 hanging on large datasets

Running a daily export job using the Python SDK to pull interaction analytics and dump them into S3 via boto3. The script works fine for small date ranges but hangs indefinitely when pulling data for the last 30 days. No exceptions thrown, just silent failure after the initial request.

analytics_api = platform_client.AnalyticsApi()
response = analytics_api.get_analytics_interactions_query(
 body=body
)

Checked CloudWatch, no errors there. Is there a pagination limit I’m missing in the SDK?
