When I start process an incident occurres with message: Expected result of the expression ‘date(“2023-11-29”)+duration(“P12H”)’ to be one of ‘[DATE_TIME, STRING]’, but was ‘NULL’
You are trying to add 12 hours to a date for which you have not specified the time…
The question is… you want to add 12 hours from what time of day 2023-29-11??
Try doing it this way and see if it works:
date("2023-11-29T00:00:00")+duration("PT12H")
I’m not sure as I don’t have much knowledge of Camunda 8, but I hope this helps.
Unfortunately this is not solution
date(“2023-11-29T00:00:00”) is not valid it returns null. Valid formula is: date and time(“2023-11-29T00:00:00”)+duration(“PT12H”)
But this is not what I need. I need to combine date and duration. It should be possible accortidng to documentation Temporal expressions | Camunda 8 Docs but it returns null.
Hey there, editing this message because someone on our end found the issue.
There is a typo in the screenshot and text, it should be PT12H not P12H.
Alternatively, you can just use date and time("2019-10-01T12:00:00Z") or any other valid ISO 8601 format and define it as a single expression. Hovering over the values gives you some additional help on how to do that.
