Hi @all,
as described I can’t delete a device. When I created this Device, an error in TTN_Homepage Occurs. After reloading the Page, the Device is lsited, but I can’t connect to it. Now, when I try to delete it, there is an error message:

An error occurred and the request could not be completed. If the error persists, please contact support.
We’re sorry for the inconvenience.

Error ID: error:pkg/rpcserver:rpc_recovered
Correlation ID: d347d014cbac418dbc466c71b83466ec

{
  "code": 13,
  "message": "error:pkg/rpcserver:rpc_recovered (Internal Server Error)",
  "details": [
    {
      "@type": "type.googleapis.com/ttn.lorawan.v3.ErrorDetails",
      "namespace": "pkg/rpcserver",
      "name": "rpc_recovered",
      "message_format": "Internal Server Error",
      "correlation_id": "d347d014cbac418dbc466c71b83466ec",
      "code": 13
    }
  ]
}

I don’t need this Device, I just want to delete it, and after that, I want to recreate it in a new try.
I hope someone can help me. Thanks a lot and kind regards,
Bastian
