# 409 group_limit_reached

> The environment, group or person is at its bound.

HTTP 409Not retryable

## What to do

Delete groups you no longer need, or split the list of people across groups.

## In the SDKs

The Node and Python SDKs raise `ConflictError`. The Go SDK returns `*apierrors.ConflictError`, which you match with `errors.As`.

```json title="409 group_limit_reached" theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
{
  "type": "https://docs.noresponse.org/problems/group-limit-reached",
  "title": "Group limit reached",
  "status": 409,
  "detail": "An environment holds at most 1000 groups, a group at most 20000 people and a person at most 1000 recorded decisions.",
  "code": "group_limit_reached",
  "request_id": "5e8be3a91fde9499f7ce48ae66290895"
}
```

Every error has this shape. [Errors and limits](https://docs.noresponse.org/reference/errors.md) lists every code.
