Azure – Synapse Pipeline Trigger parameters

We have synapse pipeline that works fine if manually triggered . But when ran in a schedule has the following error message and fails .

I verified the parameter names and the parameter does exist in the definition . Any help will be great.

‘The template language expression ‘pipeline().parameters.storageaccount_name’ cannot be evaluated because property ‘parameters’ cannot be selected."

    This was a blunder in my workflow . According to the documentation that trigger can pass parameters to pipeline and not the otherway around . In my trigger definition json I was referring to pipeline parameters ( somewhat similar to referencing an undeclared variable in programming context ). Hence it broke . After removing the references to the pipeline parameters the triggers worked .

    If you want to pass parameters to a pipeline from the trigger then define them in the trigger and the pipeline can reference them with a notation @trigger().parametername .

    Hope this helps someone.

    Check in the JSON definition; you can modify from JSON also.
    I’ve had some problems, and solved them by going to the JSON directly and modifying it there, or finding differences that were not synchronized.
