How to solve the error

@Shubham_Bidwai

Can you please share more details…like which activity is failing and what you are passing…

Also please check inner exception details from locals panel which might have more information

Cheers

Hello @Shubham_Bidwai.
Are you trying to add or subtract the Date time value? Check the Expression is like Datetime.now.adddays(-1). This error is because you try to add or subtract the date time with Undefined values like New DateTime.Adddays(-1)
