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

Possible null reference return.

Possible null reference argument for parameter 'topic' in 'MessageHeader.MessageHeader(Id messageId, RoutingKey topic, MessageType messageType, Uri? source = null, CloudEventsType? type = null, DateTimeOffset? timeStamp = null, Id? correlationId = null, RoutingKey? replyTo = null, ContentType? contentType = null, PartitionKey? partitionKey = null, Uri? dataSchema = null, string? subject = null, int handledCount = 0, Id? workflowId = null, Id? jobId = null, TimeSpan? delayed = null, TraceParent? traceParent = null, TraceState? traceState = null, Baggage? baggage = null)'.

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

Nullability of reference types in type of parameter 'value' of 'void GreetingEventMessageMapper.Context.set' doesn't match implicitly implemented member 'void IAmAMessageMapperAsync<GreetingEvent>.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).
