Msteam Notification: Publish not read parameter as Main branch

Hello

I'm using the Msteam notification as set out in document 

https://learn.microsoft.com/en-us/azure/data-factory/how-to-send-notifications-to-teams?tabs=synapse-analytics

With in the name Im using   (at)pipeline().Pipeline 

In any branch up to Main branch it work correctly giving pipeline name. But when it is publish it return the name as string '@pipeline().Pipeline'

Example of how it looks in pipeline parameter

Yes it it done in the editor

Is it showing to do with trigger in publish. but then again the '@string(Pipeline name )' works fine.

Does anyone else have this issue and is the only fix to add pipeline name to each and skip the (at)pipeline.Pipeline.
