Creating new events from bubble

I have set up scenario when user add schedule on Bubble, it will create an event in Google calendar.

I had it set up successfully for a while, then it suddenly shows me the error saying parameter “endtime” is missing.

It suddenly stopped showing up on the “value” section and i have no idea how to bring it back.

why does this happen and how can i fix this?
