Parameter value in Data Factory Triggered pipeline

by giantLincecum   Last Updated July 12, 2018 00:06 AM

I have a pipeline configured in azure data factory which basically does create a backup file (JSON) from a cosmosDB dataset and it's saved in a blob storage, my problem comes when I want to schedule the copy task in a trigger, I see that I have to specify the value for windowFunction (parameter already defined to name the JSON file with the date of the execution. ) as shown below:

Destination path:

And as you can see when I want to trigger it does ask me to specify the value for windowStart.

I tried below functions to specify that with no success so far:

"@{pipeline().parameters.windowStart}"
"@{formatDateTime(pipeline().startTime,'o')"
"@{formatDateTime(utcnow(),'yyyy-MM-dd')}"
"@{formatDateTime(trigger().startTime,'yyyy-MM-dd')}"

And the error I always get is as shown below:

Have anyone any idea or way to fix that, or have someone faced the same issue before ?
