Map and Symbology not displaying - previously working fine

luckachi

I have a web map displayed on our website that performs queries and returns the results as graphics on the map. Currently, when you first go to the website, the map and all of the different sections load and display fine. However, as soon as you select an option in our "Search by" widget, the map goes blank and nothing is displayed. The queries are working fine because the data that should be shown on the map is showing up in the dgrid just below the map. If you select a record from the table below, it will zoom to the correct location and the map loads, but the symbology for the feature does not. We were running 4.24 with a dgrid (4.17) and I thought that may have been the issue so I changed it to 4.28 but that did not corrected the problem - it only threw a ton of dojo errors. Nothing else in the code had changed in quite a few months. Nothing is returned in the console, so I am not quite sure what is going on?

Any suggestions or help?

@KenBuja Looks like it may be an issue with 10.8/10.9

Stumbled upon this thread https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/query-features-for-featurelayer-returns-wrong-y/td-p/1122441

and added the below lines of code and it seemed to fix it..

esriConfig.request.interceptors?.push({
        before(params) {
          if (params.url.includes("query")) {
            params.requestOptions.query.f = 'json';
          }
        }
      });

It looks like you're having a spatial reference problem when making graphics from the query results. If you zoom out far enough, you'll see the records, but they're in a straight line. If you click the home button, the map shows up again.

Examining one of the points in the query results shows its latitude and longitude are kind of screwy.

Well that is bizarre as nothing in the code and changed and it was working fine a week or so ago. 🤔

So I added the spatialReference to my view... and that didn't seem to change anything - it just made the initial map stop loading so I removed it.

We did upgrade our server, where the data sits, from 10.7.1 to 10.9 yesterday so I thought maybe something was messed up there but I just re-published the service and nothing changed.

It looks like "-8" is getting added to the beginning of the latitude of each point. When I examine one of the points in the response, its latitude attribute is "46.53949113" while the geometry latitude is "-846.5394911299999". I can't figure out where that is happening, since looking at the same point from the rest service shows the correct values.

And you're getting lots of dojo errors when you used v4.28 since dojo has been been almost fully removed from the SKD

How bizarre. I will try and mess around with it some more to see if I can figure out what is going on. Seems strange that it would just randomly start doing this.

Yes, that is unfortunately why we have remained at 4.24 for this map. At some point we will need to find another solution so we can use the latest version.

I double checked both feature services and both have a spatial reference of 4326. 😕
