Condition not working

[MrtnM]

Hi, I have built a simple Flow that sends an e-mail to the person assigned to the task, when a new task is created in a Sharepoint task list. That works perfectly.

However, when there is no person assigned, I get an error. I have tried different ways, but nothing works. I do not understand why: logic tells me that that when the condition is not met, the Flow should go to "If no". But instead I get an error.

"Assigned to" is an optional field.

Right now, I've tested this:

This works fine when there is a person assigned, but renders this error message when "Assigned to" is empty.

I would change your condition to trap a null value which is not the same as a no value. So if Assignedto is equal to [expression] null then etc etc.

Thanks! I'll try that! But actually, I have no idea how to write a null value ... I'd be happy for detailed steps.

Also, I noticed that the "Edit in advanced mode" link is missing from the conditions block. Maybe I need that for the null expression?

No you don't need the edit in advanced mode. In your condition select the AssignedTo field in the left box and is equal to in the middle box. Then in the right box click on Expression (next to Dynamic content) and type null. That will bring up an item for you to select. Then click OK.

Oh, thanks (blushing). I never noticed the tab "Expression" before.

Everything works just perfectly now.
