CORS Error: Accessing 'http://localhost:8888/task/findAllTask' from 'http://localhost:8080'

This error message suggests that there is a Cross-Origin Resource Sharing (CORS) policy violation when trying to access the URL 'http://localhost:8888/task/findAllTask' from the domain 'http://localhost:8080'. The server at the URL is not allowing the request to be made due to missing 'Access-Control-Allow-Origin' header in the response to the preflight request. To fix this issue, the server should be configured to respond with the appropriate headers to allow cross-origin requests from the domain 'http://localhost:8080'.
