<https://github.com/flyteorg/flyte/issues/3289|#3289 [BUG] Archive LaunchPlan>
Issue created by <https://github.com/james-union|james-union>
*Describe the bug*

We need to be able to archive launch plans as well as workflows or tasks. Currently, we don't have ability to archive launch plans on the backend side.

Here,  
The following `PUT` method for `<https://development.uniondemo.run/api/v1/named_entities/3>` fails with the error

```
4Resource [LAUNCH_PLAN] cannot have its state updated4Resource [LAUNCH_PLAN] cannot have its state updated
```

*Expected behavior*

I expect the API should update the state of Launch Plan successfully so that we can implement archiving launch plans on the UI side to follow this UI ticket.
