Azure SB integraton fails when marshaler="json" set

Good evening.

I am running into an issue where, when I set the marshaler=“json” setting under the integration configuration, my integration with our Azure service bus fails with the error below. If I comment out this line in the config, the default marshaler works. I am worried the default is json_v3 and I saw this will no longer going to be supported with the next major release

time=“2021-07-23T17:11:41.886847579Z” level=error msg=“integration/multi: integration error” ctx_id=85a1ada1-0a07-4388-84cd-b519278a3180 error=“http request error: Post “https://XXXXXXXXXXXXXX.servicebus.windows.net/device_up/messages”: context deadline exceeded” integration="*azureservicebus.Integration"

Any help would be much appreciated.
Thank you.

[EDIT]

I presume json_v3 is being used by default as I was getting the below error in AS 3.15 before it was fixed in 3.16

PostgreSQL integration “unknown message type: gw.UplinkRXInfo” error when json_v3 marshaler is configured.

You will see this error when the API call to the service-bus API times out (thus the API takes too long to respond).

PostgreSQL integration “unknown message type: gw.UplinkRXInfo” error when json_v3 marshaler is configured.

I believe this issue was addressed in the latest AS release.

OK, thank you. This time out happens as soon as I set the marshaler to ‘json’. If its set to json_v3 the integration works perfectly.

Any idea how to troubleshoot further?

Thank you.
