Nullability of reference types in type of parameter 'value' of 'void CompetingConsumerCommandMessageMapper.Context.set' doesn't match implicitly implemented member 'void IAmAMessageMapper<CompetingConsumerCommand>.Context.set' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'value' of 'void GreetingEventMessageMapper.Context.set' doesn't match implicitly implemented member 'void IAmAMessageMapper<GreetingEvent>.Context.set' (possibly because of nullability attributes).

Possible null reference argument for parameter 'topic' in 'MessageHeader.MessageHeader(string messageId, RoutingKey topic, MessageType messageType, Uri? source = null, string? type = null, DateTimeOffset? timeStamp = null, string? correlationId = null, RoutingKey? replyTo = null, string contentType = "text/plain", string partitionKey = "", Uri? dataSchema = null, string? subject = null, int handledCount = 0, TimeSpan? delayed = null)'.

Possible null reference return.

Non-nullable property 'Context' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the property as nullable.
