I’m trying to create a deployment for a group.  
I got a error 500 with the following resonse

```
{"error":"internal error","request_id":"e5855893-3887-439a-9c37-53ccb7557dde"}

```

Any hint to make it work ?

A few other information with this :  
i’m using mender community 2.5.0.  
When i try to delete and empty group with the following call :  
`https://[mender_hostname]/api/management/v1/inventory/groups/[group_name]/devices`  
, i get the same type of error :

```
{
"error": "no device IDs present in payload",
"request_id": "1d8e338b-95bb-42a7-8de0-48faeecbe98f"
}
```
