Hi,
We have a 4.5.2-1405 version of the Java SDK, and tested the sample code of the Pub/Sub. We found the JSON format of pub/sub is wrong as below.
{“MessageId”:”abf2ae8d-7cc5-4901-b172-4dc18233cc42″,”MessageType”:”ua-data”,”Messages”:[{“DataSetWriterId”:”2″,”Timestamp”:”2021-05-25T12:05:15+0800″,”Payload”:[“Voltage”:{“Value”:{“Type”:11,”Body”:227.0},”SourceTimestamp”:”2021-05-25T12:04:54+0800″}]}]}
The Payload content is in the wrong format.
Please help, thanks.
Best regards,
jelan

Hi, thanks for the report. It seems that we don’t yet support the non-reversible encoding – is that what you are expecting or can you show the whole JSON message that you expected to see?

Hi,
We except the Payload value should be a JSON object, not a JSON array.
SDK generated:
{“MessageId”:”abf2ae8d-7cc5-4901-b172-4dc18233cc42″,”MessageType”:”ua-data”,”Messages”:[{“DataSetWriterId”:”2″,”Timestamp”:”2021-05-
25T12:05:15+0800″,”Payload”:[“Voltage”:{“Value”:{“Type”:11,”Body”:227.0},”SourceTimestamp”:”2021-05-25T12:04:54+0800″}]}]}
^ this [ should be { ^ this ] should be }
We expect:
{“MessageId”:”abf2ae8d-7cc5-4901-b172-4dc18233cc42″,”MessageType”:”ua-data”,”Messages”:[{“DataSetWriterId”:”2″,”Timestamp”:”2021-05-25T12:05:15+0800″,”Payload”:{“Voltage”:{“Value”:{“Type”:11,”Body”:227.0},”SourceTimestamp”:”2021-05-25T12:04:54+0800″}}}]}

Ah, OK. Thanks for the details. Unfortunately, the fix didn’t quite make it to the 4.5.6 release of today, but if you send email to uajava-support at prosysopc dot com, we can provide you a new beta build that fixes the issue.

This has now been fixed in release 4.5.8, along with a few other MQTT and JSON related improvements, so please make sure you have the latest version.
