Programmable Chat: Conflicting member modification
The requested member is already being added or removed from this channel concurrently with another API request. The last request will be rejected to avoid inconsistent state.
Possible Causes
You might be adding a new member to the channel while the member with the same identity is being removed from another thread.
You might be submitting multiple concurrent requests to add a member with the same identity to the channel.
You might be submitting multiple concurrent requests to delete the same member by SID or identity from the channel.
Possible Solutions
Implement an operation retrier and repeat the failed member API requests after an interval of time, using an exponential backoff algorithm.
Review your application logic that caused the race condition when adding or removing members. Perhaps the conflicting operations are happening in a loop that could be avoided.
Serialize your API requests that add or remove members. Wait until the original request completes and returns an API response, before sending any successive member requests.
