Bad Request when I use iCalUid in Get Event

[SharonS]

Scenario: Creating a event registration sign up list. The event information on the registration list are look up columns from the calendar where the event is posted.

Requirement:  When a user signs up for an event, I need a calendar invite to go to the student.  When the student Accepts the invite, I need that calendar event attendee list updated on the instructor's calendar.  If I don't use the iCalUid in the flow, the instructor a calendar event gets created in his calendar for every student who signs up.  That student is in the attendee list for the event that they created in the instructor's calendar.  When I create a flow using iCalUid for the event in the instructor's calendar, I get Bad Request for Get Event.  What am I doing wrong?

Hi @SharonS

In the "Get Event" Action, you're passing the wrong input parameter. It expects the Item id as "string" and you're passing the filter query instead. The Get Event Action is used to retrieve the specific event from a calendar. If you want to query events from a calendar, then please use Get Events (V4)   Action.

My flow ran successfully after I changed it to Get Events (V4).  What I found that is strange is the date of the event after the user accepted it was not the time of the scheduled event.  I used the same iCalUid as the event on my calendar (I am the meeting organizer) but when the user signed up for the event, the time was off.  I checked my flow and the time zone (Pacific) was in the flow.  The user is on CDT and when she signed up for the event it showed up on my calendar as 2200 PST instead of 0800 PST.  I'm waiting on other testers to trigger the flow and will see what time it shows up for them.  What I found as odd is that when the first user signed up for the event, my event changed from 0800 to 2200 start time on my calendar.

Will provide an update when others testers trigger the flow.

Here is the last step 

Also I didn't remove the space but what I did was after I pasted the iCalUid with the quotes in the field, I manually deleted the single paren and added the single paren back in before and after the iCalUid.  This is how it cam into my calendar when the user signed up for the 0800 event

I am still working to resolve this issue.  A co-worker recommended that I either use custom code to get the time and date resolved using the flow or to use a Power App to get around the flow trying to pull from a lookup columns.  The Power App would pull directly from two datasources and does not pull from lookup columns. Still working on this.
