I recently ran into an issue using Cesium where I no longer see any ION map tiles and receive the following error in the console:
GET https://api.cesium.com/v1/assets/2/endpoint?access_token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJqdGkiOiJkZDJhY2VhYy0wYzljLTRiNWUtYmNhOC04OTQyZDk1YmZhMDkiLCJpZCI6MjU5LCJzY29wZXMiOlsiYXNyIiwiZ2MiXSwiaWF0IjoxNTUxNDUyMjc4fQ.B5BkE4TUBja1yOnT9sC6t8rrWghvVep21tzBq6r7aHo 401 (Unauthorized)
I have never set a defaultAccessToken for Cesium.Ion and I am not using any custom imagery providers. The map tiles have worked for a long time and I am just now seeing this issue within the last month or so.
I know that I can create a Cesium ION account and create an access token, but I am wondering why the default access token no longer works for me.
The version of Cesium that I am using is 1.55.0.
