**API Endpoint(s) and/or Zoom API Event(s)**

- [List channel members](https://developers.zoom.us/docs/api/rest/reference/chat/methods/#operation/listChannelMembers)
  - GET /chat/users/{userId}/channels/{channelId}/members

**Description**  
Recently we experienced a high volume of HTTP 400 errors while listing channel members.  
The errors appear to be happening in specific channels.

**Error?**

```auto
{
    "code": -1,
    "message": "Duplicate key {REDACT} (attempted merging values {id: {E}{REDACT}{/E}..."
}

```

**How To Reproduce**  
`curl -H "Authorization: Bearer $token" https://api.zoom.us/v2/chat/users/{userId}/channels/{channelId}/members?page_size=100`  
I can provide you with the specific endpoints that include `userId` and `channelId` , where we are encountering errors via DM if it’s helpful.

Thank you.

It seems like there are issues with listing channel members using the API endpoints provided. The HTTP 400 errors and the specific error message indicate a duplicate key problem. To reproduce the issue, the curl command with the appropriate authorization token is being used. If needed, I can share the specific endpoints, including the [OpenAI](https://opchatgpt.com/gpt-login/) userId and channelId, where the errors are occurring via direct message. Thank you for your attention to this matter.

Hi @elisa.zoom  
I don’t think this issue is resolved. I still see this error a hundred of times in the past 3 days in our system log. Could you please check this issue again?
