Please check the gRPC API, I get response in GRPC like

{
    "connections": [],
    "status": "all_connected"
}

Please use postman or some other tools to test gRPC API response

Do we need to this to export struct ?
Does it can be internal struct type connectionStatus struct ?

Am able to getting a response on my end but let me confirm if its a bug

[arvindh123]

For the gRPC request with body with group_ids like below

{
    "thing_ids": ["{{thing_id}}"]
}

Getting response like

{
    "connections_status": [],
    "status": "all_connected"
}

Is it possible to add validation in gRPC requests?
