Not able to Make Date field empty in Azure Devops using Flow

Using "Azure Devops" as as connector and  "Update  a work item" Action from Power Automate

 

If trying to update date field in Azure devops to empty value ,it doesn't work . It says same as previous values or flow fails if empty string is passed

 

error message shown if empty string is passed - :{"message":"At least one operation is required for Apply.\r\nAzure DevOps "

 

Tried couple of work arounds using following links ,but didn't help

Hi @Vishys 

 

Instead of leaving it empty try the "null" function.

 

Cheers
Manuel

Hi @manuelstgomes ,

Thank you for your reply.

 

I had tried null and empty string values both before and didn't work. It works for any text field but since this is a date field in azure devops, its not working.

I am getting the same message with no understanding as to what the issue is. 

At least one operation is required for Apply.
Azure DevOps ActivityId: 
Details: {"$id":"1","innerException":null,"message":"At least one operation is required for Apply.","typeName":"Microsoft.VisualStudio.Services.Common.VssPropertyValidationException, Microsoft.VisualStudio.Services.Common, Version=14.0.0.0, Culture=neutral, PublicKeyToken=","typeKey":"VssPropertyValidationException","errorCode":0,"eventId":3000}
