I am struggling with creating a repeat event flow for SharePoint calendars. Just when I figure out one thing, another issue arises. Most of them, I have been able to figure out, but I keep getting an error that the "ticks expects a parameter." I'm not sure which of the parameters it's wanting from the flow, exactly.

The Likely Culprit: The body() Reference

The most common reason for this error is how you are referencing the output of the previous action.

Direct Body Reference: If Add_to_time_Start is a standard "Add to time" action, referencing its body usually returns an object, not a simple string. ticks() requires a specific string format (ISO 8601).

The Fix: Try using the specific output property instead of the whole body. Usually, this is outputs('Add_to_time_Start')?['body'] or simply selecting Calculated time from the Dynamic Content picker inside the ticks() parenthesis.

The 'u' Format String: In your convertTimeZone function, you are using 'u' as the format. While this is a valid sortable format, ticks() sometimes struggles if the string includes certain characters or trailing offsets.

The Fix: Use the standard ISO format string 'yyyy-MM-ddTHH:mm:ssZ'.
