Getting the Error for a null value for drive item

Hi I am getting the below mentioned error because I am getting the null value in a drive item
Assign: Object reference not set to an instance of an object.
How to resolve it?

Hi @Kunal_Jain

What you are going to achieve in that? Can you elaborate little bit more?

In the If activity you can use like this



Hi @Kunal_Jain

What is the variable Refer datatype ?

Is it boolean?

if it is boolean why have you passed like this?

You can directly pass the Refer

and what is the variable that you have assigned in Find files and folders activity?


I have to check if the find reference variable is empty or not
And after finding if it is empty or not carry on with the further process

If possible share the sample XAML file? @Kunal_Jain

Can you tell us what is the expression that you have passed in the Assign activity



It is the first reference of find files and folders
It is the First file or Folder matching the specified Query

What is the variable that you have used in the activity find files and folders activity? @Kunal_Jain

Delete the Assign activity and directly pass that value in the If activity and check it

Still getting the same error

Hi @Kunal_Jain

Can you share the expression in the If activity and Assign activity

In the if activity I have used
And I have deleted the assign activity

What is the output comes from this variable?


Thanks for your Help
I got the solution instead of checking the first reference variable i.e. Drive item,we can check myfiles variable i.e. array of drive item.
And to find if the array is empty or not simply use
strArray.Length = 0
