SAP trigger "When a message is received" does not register in SAP when using SNC

[JWScheijgrond]

Describe the Bug

We have multiple logic apps connecting to SAP and have started to add connections that use SNC.

We have a working SNC connection (including the PSE) that is able to send RFC messages. When we try to use a SapTrigger nothing happens and nothing is logged. We have set the logging to Level4 and Verbose. We see the connection check in the logging but after that nothing happens.

The workflow when saved or after a restart or stopping and starting the logic app does nothing. If we change the connection to not use SNC the workflow registers with SAP. And we see logging.

Plan Type

Standard

Steps to Reproduce the Bug or Issue

1. Create a SAP PSE and add this to the environment
2. Create a new workflow
3. Add the SAP Trigger
4. Create a new SNC SAP connection (this is seen in the logging and is validated)
5. save the workflow

The workflow does not register with SAP....
When using a non SNC connection then it works.
