Graphql cors error while fetching data from payloadcms

Title: Help with CORS Error in Payload CMS GraphQL API on Localhost

Question:
I'm working with Payload CMS and have set cors: * in my build configuration. However, when I try to fetch data using the following GraphQL API request:

API URL: http://localhost:3001/api/graphql

Request Body:

{ "query": "query GetMcqSubmission($student_id: McqSubmission_student_id_operator!) { McqSubmissions(where: { student_id: $student_id }) { docs { pointsScored } } }", "variables": { "student_id": { "equals": "672b8c3807cb9b85c8d415fd" } } }

I’m seeing a CORS error in the browser, even though CORS is configured as *. Could anyone help me troubleshoot this issue or suggest a fix?
