Hi Wen Loo, this may not be the issue with the Date Input. Seems that you have an onchange event on the Date input and do some update to Database. And, the scenario seems like the Governance is totally new, you're in create new Governance logic (not Updating an existing Governance) and you're trying to update the Date value of a Governance record that not exist in Database yet.

Hi,

The error shows that , you are trying to create a record, and in that entity you have used the reference, but that is not found.

Can you send the pic of onchange event. so that we can correct you exactly.

Hi Jia Wen Loo,

To avoid confusions, you can detail your problem statement or can share the OML for Quicker solution and responses.

Thanks.

Hi  Jia Wen Loo,

Possible you are trying to use Entity Get Action and you are not passing sufficient value in it.

Please check and try to add Aggregate to check value.
