Not able to dispay pbf(mapbox vector tile) using openlayers
Question
i am trying to display my own created vector tiles(.pbf), they are not getting displayed with no error on console of inspect element. I am dispaying them by using a simple example html file at: here
I just have changed the url to look for vector tiles on the local server instead of mapbox server.
When i try to display the pbf files from mapbox server: , it gets displayed. Also i have downloaded these mapbox pbf files and served same files from local server they get displayed.
But the pbf files which i have created from geojson file using tippecanoe cant be displayed by openlayers.The generated pbf files are correct as i am able to dislay them using mapbox js script. I have cors on,server's content encoding is also gzip. Sample pbf file which is not getting displayed by the attached code but by tileserver-gl(mapbox script) can be downloaded from here
code:
<!DOCTYPE html>
<html>
<head>
<title>Mapbox Vector Tiles</title>
<link rel="stylesheet"href="https://openlayers.org/en/v4.5.0/css/ol.css" type="text/css">

您使用的是OpenLayers 4.5，而不是OpenLayers 5.X，请尝试上传您的OpenLayers版本。
