hi cesium,
I do it step by step through this document.cesium-workshop
I use node.js & vue and cesium-workshop-master
But when I replace defaultAccessToken(1-1,1-2) ,My web page has a mask over it,And i can’t operate on it.(1-3),
And I changed all the permissions, also can’t operate.what should i do?
