Hello,
This was working to preview yesterday, all the flows in similar notion stopped previewing but the flow is working fine to run them. Only thing I can think of is a Celigo patch in the backend potentially having broken this.
/Orders/ReadyForCeligo&lastUpdated=>{{dateFormat 'YYYY-MM-DD HH:mm:ss' lastExportDateTime 'America/Chicago' 'YYYY-MM-DDTHH:mm:ss' 'America/Chicago'}}
Error message: Details: handlebars Helper {{dateFormat}} expects date argument when you have i/p date format."
