Unable to add a user to a group in a Linux docker container dotnet-isolated process .NET 6.0 and Functions V4

Arash-Sabet commented 2 years ago

Describe the bug

The code fails to add a user to a signalR group in a docker container despite the negotiation passes successfully.

The function's code is per the snippet below:

[Function("AddToGroup")]
public SignalROutputEntity AddUserToGroup(
    [HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = "addtogroup/{groupName}/{myId}")]
    HttpRequestData req,
    string groupName,
    string myId)
{
    var output = new SignalROutputEntity();
    output.Notifications.Add(new
    {
        userId = myId,
        groupName = groupName,
        action = "add"
    });
    output.Response = req.CreateResponse(HttpStatusCode.OK);
    return output;
}

public class SignalROutputEntity
{
    [SignalROutput(HubName = "myHub", ConnectionStringSetting = "AzureSignalRConnectionString")]
    public List<object> Notifications { get; set; } = new();

    public HttpResponseData? Response { get; set; }
}

The following exception is thrown when calling this function by POSTMAN despite the function works fine out of the docker context e.g. VS 2022. Please note that there is a reverse proxy in place to accommodate CORS that performs well as other functions are working properly.

@Y-Sindo just wondering, is this a question that you may know the answer? Thanks.

Microsoft.Azure.SignalR.Common.ServiceConnectionNotActiveException: The connection is not active, data cannot be sent to the service.

Your function host didn't successfully establish WebSocket connection with Azure SignalR Service. There might be some network issues in your container. You could enable Debug log level to check the logs when the host was trying to connect to SignalR Service to see why.
