Remove duplicate values from list

I am trying without success to remove duplicate values from a list.
My list is bound to a data variable which gets it data from airtable.
The UNIQUE BY KEY doesnt work. It says the p_phone field is not createdTime, id, or fields.

I want to remove duplicate entries with the same phone number.


If you look at the schema for the data variable and airtable Get Record collection response, I’m guessing the p_phone is found within the property fields. Try UNIQUE_BY_KEY again with fields.p_phone.
