When I open the html file with localhost:3000, I worked well,.
But if I open the index.html file which is in the build file, I have errors.
One is "Access to internal resource at 'file:///C:/manifest.json' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, chrome-untrusted, secure, https." and the others is "Failed to load resource: net::ERR_FILE_NOT_FOUND". -> have four errors....!
How can I fix the errors? Where is the error spot?
