Getting a popup to work with related tables

Question

This is my first attempt at a Javascript app, so I am very new at this. We are trying to upgrade an old MapObjects site that sees a lot of traffic. Mainly, people click on a parcel and it shows them all the information about that parcel. There are several tables that are linked to the parcel layer. I have tried creating a Map Service (hosted on our server) that has the parcel layer with a relationship class to the tables, and I have also tried creating a feature layer (hosted on AGOL) that is created from the parcels with those same relationship classes. Neither of these have worked. I may not have set these up correctly either. If I point the url to a parcel layer with no related tables, it works. As soon as I change that url to the map service or the feature layer with related tables, nothing shows in the popup. What is the best way to go about getting a popup with related tables? Any help is appreciated. var parcels = new FeatureLayer({ url: "https://services3.arcgis.com/xyz/arcgis/rest/services/Parcels/FeatureServer", id: "taxlots", outFields: ["*"], popupTemplate: { // autocasts as new PopupTemplate() title: "Parcel Number: ", content: [{ type: "fields", fieldInfos: [{ fieldName: "ASSESSOR_N", visible: true, label: "Assessor Number" }, { fieldName: "relationships/0/FIRST_NAME", visible: true, label: "First Name" }, { fieldName: "relationships/0/LAST_NAME", visible: true, label: "Last Name" }] }] }, });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

An updated version of it, yes.  It is where I initially grabbed the code.  I'll try looking through it again.

Cynthia,

You have compared you code to this sample right?

Popup with related fields | ArcGIS API for JavaScript 3.23

Yes, you are right.  My updated version does have a /0 at the end, but there is still something about the related tables that it does not like.
