HI @NurNina
Do you have location services enabled and gave the Flow's app permissions to access the device's location?
I would recommend that you validate the create so that, if there's no data, you won't use that data.
Something like this:

And you'll get a run like this (from my iPhone with location services enabled)


The formula is as follows:
length(triggerBody()['location']['fullAddress'])
In this case, the condition returned true because the device returned a location
