Cors Issue Between Ui And Couchdb

I have CORS issue between UI and couchdb. But in couchdb CORS is enabled, and UI has res.header('Access-Control-Allow-Origin', '*'); header. But I still have an error XMLHttpReque

Solution 1:

Not 100% sure about this but try instead using * use localhost:5984 in Access-Control-Allow-Origin header. because for some security reason you can allow all requests. need to indicate specific domain
