Hello,

I want to trigger my flow using Trigger Conditions. I want the flow to only run when my custom Person column is filled out and contains information.

The flow is looking at a SharePoint list library. My custom column is a "Person or Group" column named: "AssignedTo"

When items are created in this list, the Assigned To column is <blank>. After the Assigned To column is filled out and saved, I want the flow to run.

I have tried many things, looking at length(), IsBlank(), equals(). But have yet to find anything that works.

Remember I want to use the built in Trigger Conditions.

Thanks for any help!

Right. So that expression works if I want the Flow to be trigger when the people picker is empty. But I want to trigger the flow when the people picker is not empty. The people picker must be filled in before flow is triggered.

I added the @not in the beginning. This expression worked for what I need:
@not(empty(triggerBody()?['AssignedTo']))

Thanks for the assist @PrasadAthalye

Re: Trigger Conditions to start a flow when a 'Person or Group' field CONTAINS a name

I'm attempting something similar but need assistance. Like you, the "Assigned To" value is initially blank and later gets populated. I want it to send the email notification to the "Assigned To" person the FIRST time they are assigned.

However, IF the "Assigned To" person later changes....then I also need an email sent to the NEW "Assigned To" person.

Any guidance would be appreciated.

Re: Trigger Conditions to start a flow when a 'Person or Group' field CONTAINS a name

Hi @PrasadAthalye - I am working on a very similar Automation - if you could help me that would be amazing.....

I want an email to be sent to the "Additional tester" (name of the List item) when they are assigned to a List test case.
However, when I use the following trigger
@not(empty(triggerBody()?['Additionaltesters']))

it is notifying the Additional Tester every single time any field within the test case is modified, not only the Additional Tester field.

I only want an email notification to be send IF the Additional testers field is populated.
Am I using the wrong trigger? Here is my Automation path:
When an item or a file is modified (this is where the trigger is) > Get changes for an item or a file (properties only) > Condition
: Has column changed: Additional testers

Hi - can you help me to revise this for a multiple person column, where the result is an array? Thank you 🙂
