The 404 "Resource not found" error typically occurs due to one of these common issues when using the Azure Document Intelligence API:

Incorrect endpoint URL format - Make sure you're using the correct format:

endpoint="https://{your-resource-name}.cognitiveservices.azure.com/" Double-check that is replaced with your actual resource name, not left as a placeholder.

Invalid resource region - The endpoint URL should match the region where your Document Intelligence resource is deployed. Verify this in your Azure portal.

just fix it by Go to your Azure Document Intelligence resource Copy the exact endpoint URL from "Keys and Endpoint" section Use that URL in your code, ensuring no typos or formatting issues
