**API Endpoint(s) and/or Zoom API Event(s)**  
List meeting participants QoS Summary

**get** /metrics/meetings/{meetingId}/participants/qos\_summary

**Description**  
When sending the request for some meeting Ids the response has an error (with status code 400)  
Seems like an AWS bug, but this happens on meetings that happened after oct 20th

**Error?**  
`code: -1`  
`Cannot invoke “com.amazonaws.services.dynamodbv2.model.AttributeValue.getS()” because the return value of “java.util.Map.get(Object)” is null`

**How To Reproduce**  
Steps to reproduce the behavior:

1. Get a problematic meeting Id
2. Send request to QSS api and paginate throughout
3. Error should appear

Hi @Noam3  
Thanks for reaching out to us and welcome to the Zoom Developer Forum. Is this happening consistently?  
Could you please share with me a tracking ID found in the response headers of your request so I can escalate this internally?
