Vector basemap doesn't show labels, and tile 404 errors

BenRomlein — Sat, 11 Dec 2021 12:44:31 GMT

Using the 4.14 Javacript API, I have a simple page set up with a map uses a vector basemap like so:

var map = new Map({
  basemap: "topo-vector",
  layers: mask
});

I'm using the basic claro/light css styles:

 <link rel="stylesheet" href="https://js.arcgis.com/4.14/dijit/themes/claro/
 claro.css" />
<link rel="stylesheet" href="https://js.arcgis.com/4.14/esri/themes/light/
 main.css" />

with no additional styles applied to my map or view.

As of this morning, labels are no longer showing up, and as users pan and zoom, several tiles are failing to load with 404 errors.

If I switch the code to use a non-vector basemap, everything seems to work properly. And when I view the basemap in the arcgis online viewer, the labels appear fine.

status.arcgis.com reports normal operation for basemaps and I didn't change my code between when it was working and now. Is anyone else having issues with vector basemaps? Am I missing some kind of style declaration that's required to show labels?

Ben,

Nope I am not seeing this issue. When you go to https://developers.arcgis.com/javascript/latest/sample-code/sandbox/index.html?sample=intro-mapview and change

basemap: "streets-vector", do you still see your issue?

It must have just been a blip in the service somewhere. After doing nothing but reloading the page just now, things are back to normal. Thanks for the reply though!
