Error uploading to S3: AccessDenied: Access Denied at Request.extractError (/var/task/.next/server/chunks/431.js:24041:41)

Thanks for sharing your issue. I understand that you're encountering an "S3 Access Denied" error while trying to access your AWS S3 bucket from your Vercel deployment.

The "S3 Access Denied" error typically indicates that the origin of the request is not authorized to perform the action. This can occur for various reasons, but it often boils down to authentication issues or insufficient permissions.

Troubleshooting Steps: To address this problem, you can follow these steps to troubleshoot the issue:

• IAM User Permissions: Double-check the permissions and policies assigned to your IAM user in AWS. Ensure that they have the necessary permissions for S3 operations.
• Vercel Environment Variables: Verify that the environment variables (e.g., AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY) in your Vercel project settings are correctly configured with the AWS credentials.
• AWS Region: Confirm that the AWS region set in Vercel matches the region of your S3 bucket
• Vercel Logs: Inspect the logs in your Vercel deployment for more detailed error messages or stack traces.
• S3 Access Logs: Review the access logs for your S3 bucket. These logs can provide insights into the requests and their outcomes.
• Bucket Policy: Check if your S3 bucket has a bucket policy that may restrict access. Bucket policies can override user-level permissions.
• CORS Configuration: Make sure that CORS (Cross-Origin Resource Sharing) is correctly configured on your S3 bucket. Refer to the official Vercel guide for guidance. You can also consult AWS documentation on CORS for details.
