From your “Update Record Action” setup, it looks like it’s only updating the first record in your “Canada Sales Contact” database.
I think you want to use the LinkedIn link to find and update the specific record where linkedin_link matches the one from your Script/Trigger, right?
Quick fix: Add a “Get Record” action before the “Update Record” step. Set its filter to {Canada_Sales_Contact.linkedin_link} = {Script.linkedin_link}. Then in your “Update Record” action, use the Record ID from this “Get Record” output as the target record. Just make sure only one record matches that LinkedIn link, otherwise the automation might get stuck.
