We have an NServiceBus 6 environment with a number of services that send files between each other using DataBusProperty over a custom SqlDataBus : IDataBus.
This works fine on NSB6 using the built in JSON serializer, but is now broken after we moved to NSB7 and the NewtonsoftSerializer.
Removing DataBusProperty from our classes and just using byte[] works fine. We also tried changing the DataBus to FileShareDataBus but got the same exception:
NServiceBus.MessageDeserializationException: An error occurred while attempting to extract logical messages from incoming physical message c7b5cd47-c1b7-4610-9f6c-aa7800cc9b64 --->
Newtonsoft.Json.JsonReaderException: Error reading bytes. Unexpected token: StartObject. Path 'Data.Key', line 1, position 68.
This fails even if a service is sending messages to itself. Also we can see the files written to the file store, whether on Sql or File Share, so they're serializing fine.
An example payload from the error queue is
{"ExecutionId":"1db85105-a71c-4b29-87da-9b7ae6518c1c","Data":{"Key":"2019-06-26_13\\6a2b63c7-12b0-46dd-8b92-f1fc743d27c1","HasValue":true}}
How can we get this to deserialize in NSB7+NewtonsoftSerializer when it works fine in NSB6+JsonSerializer?
Thanks
