Nullability of reference types in return type of 'T? AsyncBlockingQueueEnumerator.Current.get' doesn't match implicitly implemented member 'T IAsyncEnumerator<T>.Current.get' (possibly because of nullability attributes).

Non-nullable field 'channelId' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.

Non-nullable property 'Source' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

'LightCommand' is obsolete: 'Replace with: UpdateLight'

Dereference of a possibly null reference.

Possible null reference argument for parameter 'entityId' in 'Task<PhilipsHueWorkerServiceConfiguration> IChannelConfigurationService.LoadAsync<PhilipsHueWorkerServiceConfiguration>(string entityId, string channelName, CancellationToken cancellationToken = default(CancellationToken))'.

Possible null reference argument for parameter 'entityId' in 'Task IChannelConfigurationService.SaveAsync<PhilipsHueWorkerServiceConfiguration>(string entityId, string channelName, PhilipsHueWorkerServiceConfiguration value, CancellationToken cancellationToken = default(CancellationToken))'.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.

Possible null reference argument for parameter 'json' in 'TvWsResponseDto? JsonSerializer.Deserialize<TvWsResponseDto>(string json, JsonSerializerOptions? options = null)'.
