Hi @deenhag 

Both the Start/End Date & Time expect timestamp values.

Reference the field description for guidance.



You can use modifiers to adjust the timestamp values:

the problem is not end time. problem is start time. i changed many times for different value but still same problem.

Hi there @deenhag,

I’m jumping in to see if I can help!

Whenever you see those {{...}} curly braces around entries in the Data In of an action, this means that there is a field mapped there in the Zap Editor, but when the Zap ran live this data was not sent from a previous step.

Could you please try doing these for me?

  1. Remove the typed data on the “Start Date & Time” field:

  2. Load in a new sample data in the trigger step by clicking on the “Find more records” button.
  3. Head back to the “Start Date & Time” field and map the new “Due” data.
  4. Trigger the Zap again.

Could you please give that a try, and let me know how it goes?
