Slow layer on webmap. How to switch from json to pbf output format?

matteorizzi — Thu, 27 Jul 2023 14:44:44 GMT

Hi! I am using ArcGIS Maps SDK for Javascript and I have a problem by calling a webmap from ArcGIS Portal. In the webmap there is a couple of feature layer and they are very slow due to the fact that the webmap load them by using json format. In the Rest properties I can see both of them supports the PBF format but I am not figuring out how to force this change.

How can I switch from json to pbf output format? Should I change something in the service or in the map?

Thank you

Quick update
In my case: The issue stemmed from the FeatureService, which listed only 'json' in the supportedQueryFormats attribute, even though both individual FeatureLayers included 'pbf' in their supportedQueryFormats. I resolved this by using an interceptor to forcibly add 'pbf' to the supportedQueryFormats of the FeatureService, with a code like this:

require(["esri/config"], (esriConfig) => { esriConfig.request.interceptors.push({ urls: /FeatureServer/, after: function (response) { response.data.supportedQueryFormats = "JSON,PBF"; } }); });

I think I am having this same issue. I am using OOB Experience Builder and getting PBF errors on my queries. My feature service only has "Supported Query Formats: JSON" while my layers have "Supported Query Formats: JSON, geoJSON, PBF".

Where do i make your above change?

Hi MKa,
unfortunately my solution is implemented on a javascript application and not on ExpBuilder. In any case you can place the portion of code at any time before loading your FeatureService.
