问题 I tried using a web app that would access h20 flow using REST API routes and when I tried to delete a frame (it would delete the frame after predicting), this happens: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://139.59.249.87:54321/3/Frames/1i3uso.
